Hmm, I think it might be related to this issue with Squirrel & Teams, unfortunately it’s not anything I’m able to control https://github.com/Squirrel/Squirrel.Windows/issues/1853 I think you may need to use the No Installer version instead
It's fine, don't worry. I usually have backups but have been so neck-deep into work lately I didn't remember doing one before installing the new version (I'm a simple guy; I see GB Studio updates, I download and install). I'm not concerned in regards to project files, since most of what I had were placeholders to test movement routines and collisions. The issue is really the references since they were largely my own (bitmap mockups, etc) and while I can resume this at any time, it'll be double work for that. Oh well.
In any case, not trying to be a downer. GB Studio is amazing, please keep up the great work.
