Crash on open project

I get UE4Editor-cmd.exe crash when I try to open my project.
Here is the log

Hey HorusWM,

Can you include your dxdiag information as well? Also, do you have both an integrated GPU and a stand-alone video card?

Thanks,

-Steve

DxDiag

I use only stand-alone video card.

Hi Horus,

Is this crash only occurring on your project, or does it also occur when opening any project, like the Sample and Template projects?

5

All other projects like content examples or template open without errors, only my project crushed.

Hey HorusWM,

According to your log, the crash is occurring due to:

LogWindows: Cast of Package /Game/Blueprints/General/TDController to EdGraphNode failed

I also see that you are loading a custom map as the default map for this project, which presumably is doing this casting in the Level Blueprint. You should at least be able to get back into your project by going into your \UE4\YourProjectName\Config and editing the following line in the DefaultEngine.ini:

[/Script/EngineSettings.GameMapsSettings]
 EditorStartupMap=

If you delete the EditorStartupMap= line and save the .ini, it will load to the default Engine map we use the next time you try to load your project. This will let you get back into your project to try to track down the asset that causing the casting failure.

Is this project you are trying to load a code-based project or blueprint-only?

Now I can launch the editor, but I get crash error when I try to open my PlayerController blueprint.
Log file

when I created a project I used the basic code project template, but so far only used blueprints.

Is there any solution of this error or am I going to redo PController blueprint again?

Hi Horus,

Would you be willing to send us the .uasset (in Zip file) for the Blueprint that is causing the problem? Unfortunately you may not be able to salvage the Blueprint, but we may be able to identify the issue and prevent it from occurring again.

Thanks

Here it is

Hey HorusWM,

Your controller is trying to reference your TDCharacter and TDCustomizeCamera while loading–could you include those assets as well?

Do you happen to remember how your Controller was setup before you started getting this crash? If you are able to re-make it, could you include a screenshot or screenshots of the setup?

Thanks,

-Steve

[Character and camera blueprints][1]

I change mouse rotation, added camera zoom and camera rotation before I received an error

Hey Horus,

I’m going through trying to reproduce this issue and saw a screenshot you had posted previously, before_full.jpg. Could you provide a zoomed-in screenshot of the Special move block of nodes from that screenshot? I see that’s where you’re using the Cast To node, just want to see the full context of what you were doing there to see if that provides any insight as to what may have caused the corruption.

Thanks!

Hey Horus,

Thanks for all of your information. We have, unfortunately, been unable to reproduce this corruption/crash from a fresh blueprint, but have filed a defect report for further investigation of your corrupted asset to see if we can discover the source of the problem.

We will try to provide an update for you once we have any additional information, but you should go about working with a new PlayerController in the mean time. Sorry for any time lost having to recreate your asset(s)!

Thanks,

-Steve
