I have been using 2.83 on a Mac (Catalina OS) and I closed a large 2GB file last night that I've been working on for a while, and Blender crashed. Now this morning when I try and open the file Blender keeps crashing, I can't open it at all. I've tried making a duplicate of the "blend1" file and opening that, but it crashes on that also. I downloaded 2.9 and tried opening it with that, and it crashes too.
I've put a lot of work into that file so I'm very worried that I've lost all of my work. I have been able to open previous versions of this file.
Thanks.
