Lightmass crashing! How to fix?

Hey there. Tried asking for help with this on Discord but never got an answer.

I’m having problem with my project showing up in the Project Browser and need to manually load it every time I want to work on it. While everything seems to work fine, I figured it’s probably going to cause me troubles in the future so decided to attempt to copy it over to a working project. Initially I tried migrating the level but UE5 kept crashing completely so I tried just copying the files themselves in Windows Explorer.

This seems to have mostly worked but I’m getting these two errors. Would any one have any idea how to fix these? Nothing renders properly with these errors.

Thanks!

Still no answer? Anyone?
