You can try signing out and signing back in first, and if that doesn’t resolve the issue, uninstall UiPath Studio, delete the folder C:\Users\AppData\Local\UiPath, then reinstall UiPath Community Studio from the official download page and sign in again.
Thanks. I verified and found out that I was on express plan and my 2 months were expired. I deleted my previous organization and signed in again. Now I’m on community Plan.
