To open the project try to edit the INI files and change the default level.
You’ll likely need to delete that level from existence as it seems to be causing the crash.
If you don’t want to just bite the bullet and delete it, other things to try involve deleting most of the saved directory so that shaders and “stuff” gets rebuilt.
You jeed to look up exactly what folders are ok to be deleted.
And, probably, before anything else, make a copy and work within the copy of the project.
BTW, I’d still also run an sfc /scannow and a chkdsk to repair files/sectors…
It could be the editor quit on you while being unable to write or something similar - it’s worth a try.
