Unreal crashes upon opening my project

I was working on my level when I hit “save”, after it saved the editor shut down and then gave me a crash report. When I try to re-open my project, I just get the crash reporter again. I can’t get into my level at all. This is a university final year project so it is quite urgent so I would really appreciate some help.

I have attached the log file.

EDIT: Just a follow up, I tried moving that particular level to another project folder to see if it would still crash and I could at least get in, and it still did, so it’s something to do with my level. :frowning:

Unfortunately it appears your level is corrupt.
