The crash is due to #7657 (which I have now pinned to the known issues also):

Closing as Duplicate.

And the project was not attached, so I can't say 100%, but it looks to me like just bad luck/timing, as while the project was loading you got the same crash a second time.

I strongly suspect the project itself is absolutely fine - you just need us to fix the crash asap.
