UE4 project closes at 45%

When opening my project it closes after 45%. (No error message) I can still open empty projects but not this one. How can i resolve this?

Things i tried:

-Removing Saved, Intermediate , Config, and build files
-Removing derivedatacache folder

It still doesnt’t work

45% is a common issue on Unreal. At 45%, the engine is compiling shaders. Is the engine closing itself or are your forcing it to quit?

If you’re doing it manually assuming it’s crashed, just leave it for a long time (I’m talking half an hour+ in some instances). Depending on how powerful your computer is, this can take awhile.

If it’s crashing on it’s own, I’d duplicate the project, go into content and delete shader uassets and try to reopen. This will remove all the shaders from your project and make everything look weird, but at least if the project opens, you’ll know where your problem lies.

Its crashing on its own. The process just dissapears in the task manager. But when you say delete shader uassets, do you mean the materials. How do i know which one to delete?

I have 16 GB Ram. Also tried copying all files to an empty project and it did load the editor once but then it shuts down again after 1 minute of loading content folder files. Rebooted it but now it shuts down again when it reaches 45%. Is it because of an corrupt asset or maybe a material shader?

Are you running at least 8GB RAM - you’re likely to run into issues with less.

I works now. I found a corrupt uasset file that i had to replace with one in the backup folder.
