Neil,
I was just able to solve the problem.
Things I tried-
- Starting Premiere with no drives plugged in - fail
- Quitting and forcing save - fail
- Getting uninvited and revinted to team project - fail
- Every way of saving locally / saving to teams - fail
- Deleting autosave folder in Adobe Cloud Folder - fail
- GOING INTO CREATIVE CLOUD AND SELECTING A PREVIOUS VERSION (from 22.5 to 22.4) - WIN
Don't ask me why but after 2 weeks of asking people, digging in forums, and speaking with AE's, a simple version downgrade unclogged the pipe and let me in. I now have a backlog of local saves that it's trying to upload when I share changes but I will have the team reject them and reshare their version of the project with me in the morning.
Cheers, hope this is helpful!
Sorry, to be clear, I replaced my install of Premiere (inside of creative cloud desktop app) with version 22.4 (I was on version 22.5) and that is what did the trick.
