This is a new issue with final versions of 4.10 (did not happen in 4.10 previews). Randomly, usually from interacting with assets in Content Browser or hitting PIE, editor will crash with no minidump.
Seems like it may be frequent when computer has been idle for some time.
Hi Sean,
Please copy information in Crash Reporter window, including Machine ID, next time this crash occurs. Be sure to hit Send, and reply with information here. Then get most recent log files from project’s \Saved\Logs folder, them up, and attach them.
Does this crash happen in multiple projects, or only your current project? Are you able to reproduce it in a new project? Was project converted up from a previous engine version? Thanks!
Hey Sean,
We haven’t heard back from you yet, so I’m resolving this post for tracking purposes. If you’re still getting this crash, please provide information requested above and we’ll continue assisting. Thanks!
This one happened when trying to compile a Blueprint. This project was created new for 4.10 final release, but some of .uassets were copied over from 4.10 previews.

No minidump found for this crash.
What types of .uassets were copied over to new project? I would recommend removing them from new project and Migrating them instead. It’s possible there’s some missing references or corrupted assets from moving them over manually.
Missing references as in other assets from Content Browser? I was careful to copy all of them over… or do you mean lower level references from engine?
Also, you say it’s possible for uassets to become corrupted just by copying them over to a different engine version? And Migration (as opposed to copying) prevents this?
Unfortunately, old project is gone–I trashed it, so testing this is going to be hard. My project is in early stages, so rebuilding some things from scratch would be ok. However, my UMG widget is not one of those things… I spent weeks building it up and making it perfect.
Is there an easy way to copy Blueprint (and UMG) contents into a new Blueprint uasset?
By way, I really appreciate support, thank you.
Moving assets from one engine version to another, even between preview versions and official, can sometimes cause problems. It might not even be corrupted, but just not work in newer version due to changes between versions. That’s why Migrate is a better idea when possible. It also grabs all referenced assets, and places them in same folder structure automatically. You can do this manually sometimes, but it’s easy to miss things or place them in a different folder hierarchy and not know.
Unfortunately crash you’re getting is giving us a minidump, so it’s not being reported to us at all, and log you gave us doesn’t have anything in it to help debug problem, so all of this is just a guess at what’s causing crash. It seems very likely, though, that it’s related to moved assets, and that’d be first place I’d look.
You can do some manual copying to a new BP, yes. If you have BP open, you can select multiple nodes and copy them, then paste them into a new BP. Functions and Macros will need to be recreated, and copied variables will need to be converted (right-click, Create this Variable), but you can do it.
Hmm… copying contents of Blueprints wouldn’t be a problem. It’s UMG widget layout (all non-Blueprint stuff) that is irreplaceable–I tried copying layout over but it doesn’t work. Only Blueprint nodes work.
Just out of curiosity, why is there no minidump? I used to get them on every crash, but not anymore.
Copying widget layout can be done as well. If you right click elements you need in Hierarchy tab of widget, you can copy it and it will also copy children in hierarchy. You can then paste that in a new widget. You need to be careful doing this; if you select Canvas and try to copy that, it will copy everything including Canvas, and pasting it into new widget will child all of that to existing Canvas. Let me know if that’s confusing and I’ll post a few screenshots.
I’m not sure why you’re not getting any minidumps. To be sure that you’re simply not getting them, open editor and open console with tilde key. Then enter “debug crash” and see if it gives you a mini-dump. If not, there’s probably an issue with your installation, and I would recommend trying a Verify through Launcher first.
debug crash does not generate a minidump for me. I have tried verifying installation, and completely removing and installing 4.10.1. but it’s still same.
I am trying to remember, but I think I stopped getting minidumps after reformatting and installing latest build of Windows 10.
Well, I’m not certain why you wouldn’t be getting minidumps on crashes anymore. I’ll make a note of it and see if we can figure out why that could happen. It might be an OS update thing.
Were you able to copy over information you needed for those copied BPs? Are you still crashing from these assets?
Since making that last post, I have decided to port my entire project to C++ anyway, so it’s not all that bad. I was able to extend UUserWidget in C++ and then make a Blueprint of that. Then, I copied my interface layout over and it worked nicely.
minidumps are a seemingly random occurrence. I reformat quite often, so when I install Windows again, and I start getting minidumps, I will post here.
I really appreciate support, thank you.
