I’ve recently noticed that in the content browser, when I double-click or right-click and select “Edit”, the window does not open. It appears in the task bar but I can’t switch to it. This happens with Meshes, Materials, Textures, Blueprints, and Particles. Some assets still open normally and in either case I can still use the assets in the level.
Fairly confused by this. Please help.
Hey ,
Have you tried verifying your version of the editor to see if that fixes the issue? Is this happening on every single project, or just one specifically? Have you tried restarting your computer? Please also provide me your dxdiag from your computer.
Looking forward to hearing back from you, thanks!!
Sorry, my ISP broke my internet while fixing the neighbor’s. I’ll get you the dxdiag once I get back online.
The Verify option on 4.8 is greyed-out (I guess because I’m offline?). I have restarted. I’ve only tried it in one project, but I’ll see if others are affected.
Hey ,
Once your internet is fixed you should have no trouble verifying your version of the Editor. It should not be grey once the internet connection is restored. Just attach the DXDiag once you’re able to, thanks! 
Hey ,
I have not heard from you in quite a few days. With that being said, I must resolve your question at this time for tracking and recording purposes. However, if you still have questions regarding this specific topic, please feel free to reply back here. For all other questions, please submit a new question to AnswerHub.
Have a great day!
Sorry it took so long. I verified my 4.8.0 and I’ve attached my dxdiag.txt
I’ve also enclosed a screenshot showing two assets (chair and choppa). One that opens properly while the other appears to do nothing until you notice the invisible windows stacking up in the task bar.
If it helps at all, when I close those empty windows, it will occasionally ask me if I want to save the LOD changes.

Hey,
Thanks for providing me with this information.
Have you been able to migrate the ‘choppa.uasset’ to another project and been able to successfully open the blueprint? Please try to delete your intermediate, saved and config folders from your project folder. If that works, let me know. If not, please try the following:
Also, could you zip everything associated with the ‘choppa.uasset’ and provide that whole zip file to me? If you’d like it to stay out of public reach, please provide it to me on the forums through a private message. By providing me the asset (with the materials, blueprints, etc) intact, I’m able to try and replicate what you’re seeing as well.
Looking forward to hearing back from you, thanks!
I wanted to let you know that the problem is occurring across multiple projects and that deleting the Saved, Config, and Intermediate folders caused it to happen on all assets (including the few that had still worked). Edit functionality returned to those few assets when I restored the folders. So you’re definitely on to something.
The “Choppa” mesh actually comes from Epic’s own Platformer Game example. I tried to edit “Choppa” in a fresh download of this project and the window failed to open. I can still get you the Choppa assets if you want them, but it seems that the problem lies in the process that creates whatever the relevant files are in the Saved/Config/Intermediate folders.
Thanks for your ongoing support!
Hey,
So when you deleted those files, you were given an option to return the assets deleted and that helped some of the issues you were receiving? If not, I would suggest right-clicking in the Content Browser and using the ‘fix up redirectors in folder’ option that’s listed. Let me know if that helps any.
In your original version of your project when you used the ‘Choppa’ asset, did you ever modify it? If so, what did you modify on it? I see where you tried to modify and the window never opened, I was curious if that was after deleting those folders, or before?
I would go ahead and attach the assets so I’ll have then when I receive your reply, just in case I need them. They shouldn’t take too long to upload.
If there are any output , please attach those as well.
Looking forward to hearing back from you, I appreciate all of your assistance.
Chair was an example of an asset that opens properly, whereas Choppa was an example of one that doesn’t open (though both are still usable in the level). When you had me delete the 3 folders and restart the editor, then no assets worked. When I put the folders back, Chair was able to open again. Nothing further was fixed, but something in those folders keeps Chair able to open.
The normal and diffuse of the Choppa put the zip up to 7mb, which is over the 5mb limit. However, I didn’t modify Choppa and since the actual asset from the official Epic project doesn’t open, I don’t think this is a problem with the assets themselves. This problem extends to all new projects/assets that I try to open.
I have deleted the derived data cache a couple times in the past.
Further testing reveals that it is the EditorPerProjectUserSettings.ini in ~\Saved\Config\Windows that allows the Chair asset to still open.
Compared to the auto-generated file, which is 40kb, mine is 699k and contains a list of assets under the [AssetEditorToolkitTabLocation] section. I hope this is useful.
Hey,
Thanks for providing me with this information.
It’s very odd that deleting the Config, Intermediate and Saved folders caused an issue with your assets. Where do you have your assets saved, what are the file paths?
I wanted to let you know that I migrated ‘Choppa’ into my own project from Platformer Game and I have been successful in opening the blueprint editor. Have you tried deleting the ‘Choppa.uasset’ from your game and migrating it over again from Platformer Game?
The problem extends to all new assets/projects. I really don’t think the assets are the problem; I think it has something to do with the [AssetEditorToolkitTabLocation] in the EditPerProjectUserSettings.ini
Rather than “the Edit window failed to open” it’s that “the Edit window tab got lost”.
Hey,
Could you upload the ‘DefaultEditorUserSettings.ini’ that you believe is causing the trouble, please?
Thanks!
broken settings is the auto-generated file where none of the assets will open.
partially working settings is my old file where a few of the assets open (such as SM_chair).
as you can see, there is a section towards the bottom called [AssetEditorToolkitTabLocation] that has a long list of assets followed by a 0 or a 1.
The 0 and 1 do not determine whether the asset will open. However, the auto-generated file lacks the section altogether.

Hey ,
I have submitted the log files to our developers for closer attention. I’ll either be contacting you back, or one of the developers directly. If you have any further questions, please let us know.
Thanks!
If my project is in my Perforce folder, can I delete all other traces of ue4 and it will still recognize my project when I reinstall?
Hey ,
As long as your Perforce folder is not inside of the Engine files you’re about to delete, they will be safe. My highly cautious suggestion would be to move your Perforce folder to your desktop. Then wipe the Unreal Engine from your engine. Once you’ve done that, install UE4 back and sync back up to your Perforce.
As long as you’re not deleting your files out of your Perforce folder, you should have nothing to worry about. If you have any additional questions, please let me know.
Have a wonderful day!
Just following up, we were able to solve the problem without reinstalling.
I have no idea what caused the problem in the first place, but some of the edit windows were opening as though they were on a dual monitor set up even though I don’t have that on my machine.
The solution is to right click on the missing tab in the task bar and select “Move” then tap a direction key and the tab will be brought back on screen. It will be scaled down to nothing; you’ll only be able to see the minimize/maximize/close buttons. But when you scale it back up, it should be working fine.
Doing this fixed all the missing asset windows simultaneously.
Thanks again. Peace!
