My project was working fine until today when I tried to open up my second level and encounter a crash when I try to open or delete the level, here are the crash details.
://gyazo/fb3ecb578cdd65c45a0aa71a151c4c00
This is all the folder contains

Hi,
I was able to fix one of my corrupted projects by deleting the autosave and intermediate folders.
When I opened the project, all worked again.
Just give it a try. (Make a backup of the folders just in case)
Cheers,
Klaus
Could you probably post your log file -> project-saved-Logs?
