Engine crashes when opening a BP or GameInstance

etiq · September 10, 2024, 12:34pm

I have been developing a game for months. The editor crashed while I was coding game. This crash was appearing everytime I open the game. I opened project successfully by setting level on DefaultEngine.ini to blank one. But I cant open most of my BPs, widgets, game instance and more, even a BP that a coded months before.

I am using UE5.2

I tried many ways I have seen on forums.

My project is in default projects folder. Fix up redirectors is not working, engine crashing.

I deleted Intermediate, DerivedDataCache, and Saved folders but not worked.

My kit is RTX2060 Super, i5 9400F, 2x16 gb ram, and I am using Windows 10.

I updated my GPU driver, using the last version.

I tried using my laptop, which has RTX4050 and Windows 11.

I activated and deactivated RTX long before this crash. I added FSR3, but I dont know if crash is about FSR. Nvidia DLSS was added long and long before but It was deactivated.

Details of error:

Waiting for your suggestions.

First make backup of whole project.

Then find which blueprint causes crash. Just keep deleting blueprints from folder manually, and see which one crashes. When you know which one you either recreate it, or try to migrate that bp to empty project see what you can salvage.

Hello, i also meet the same crash when clicking the bp. I found my DLSS plugins is disabled while the blueprint use it. I solve this by re-enable the DLSS plugin, hopes to help you!
