Unreal Engine 5 crashes when opening a level

It could be the filename / path name length. The path that was listed above was 248 chars. The default limit was 256 chars not counting drive letter and null termination. There appears to be a new feature after windows 10 to allow longer file/path names but you need to activate it.

I personally would try to simplify the file paths and not nest too deep in files as it becomes more and more difficult to read and traverse.

So, you could try renaming some of the longer directories to something simple and see if that fixes it.

Here is the link from Microsoft for the work required to extend the file limits. I have NOT done this, so proceed with caution.
