Okay, so that did work. I was able to create a new Team Project from that saved version. Unfortunately I had a lot of unsaved edits from that crash that would be in the auto-save but I'm assuming that may be a lost cause? At least this gets a working version up and running again. Thanks!
Glad to hear that worked! You can certainly try the same process with your auto-saves. With any luck, you'll be able to go back one step in the auto-save history and be back up and running. It might take a few more iterations to find the most-recent auto-save that works, though.
You mentioned earlier that you tried renaming your Team Projects Local Hub directory. That original directory contains all of your auto-saves, so the first step will be to quit Premiere (and any other Adobe software that uses Team Projects), then change the name of that original directory back to Team Projects Local Hub.
Next, launch Premiere, open a different Team Project or standalone project, and browse to the auto-saves for the problem Team Project (the Auto-Saves tab is next to "Versions" in the Media Browser). You can then scroll to a previous version or use the "previous version" arrow at the bottom of the scrollbar. Once you've selected the auto-save you want to try, right-click on the Team Project name and choose "Make Auto-Save (date and time) the Latest...". The next time you open that Team Project, it will be in the state it was in for that auto-save, while leaving the rest of the auto-save history in place. If that works, you're in business! If not, try going back one step further until you find the most recent auto-save that does not exhibit the problem.
