Premiere Teams Project "Unsupported Project Version" error with latest update

Hi, very frustrated by this problem, after successfully using PP Teams for the past year.

I launched PP this morning and tried to open a Team Project that our team has been working for over a month and received the "Unssuported Project version" message.  Assuming a collaborator updated PPro yesterday, I updated to ver 15.2 and tried again, and received the same message. Every collaborator is now getting the same message, whether they are on 15.2 or 15.1. I've rebooted twice, logged out/in of CC Desktop, but can't open the project, although older projects open with no issue.

I'm experiencing a similar problem. Team project that has been working for months without an issue.  Duplicated an existing segment, renamed it, and then pushed my changes and the rest of the team gets the "Unsupported Project Version" "This project was edited in a newer version.  Please update to the latest version and try again."  when they try to open the project.  We all checked our versions of CC Premier Pro 2021 and we are all on the latest update using 15.4.1 (build 6). 

After I logged out, I received the same error when trying to log back in.
