Project is suddenly corrupted

It always hangs at 93% when loading, it looks like it is still doing something but then it crashes after a minute. This is a project based on the Generic Shooter Marketplace project. The last thing I did was trying to make a build, that failed with only packaging it partially. Then I did a restart of the PC and the project would not load up anymore.
I already tried to delete the Derived Data Cache so it would generate that again as well as deleting cooked files and build files from the project but nothing helped. Is there anything else I can do to rescue my project or is it now corrupted and trash?

I get similar crash .Try to get out your content from the folder, Usually i find that the blueprint i was working is corrupted and i have to pick up from the saved folder, an older blueprint, that still work , and replace and rename the New-corrupted one.

That didn’t work for me, I replaced the BP i worked on with a autosave and deleted the map I worked on and nothing changed. But I found a way to make it work now, I deleted all the files in the Intermediate folder and then it loaded up fine again. It might be that deleting the CachedAssetRegistry.bin is the important part.
