Hey! I feel your pain—Project Online session expiring is such a headache. I had the same issue, and it turned out to be a timeout setting on the server side.
If you have admin access, check the session timeout settings in SharePoint Central Admin. Sometimes it’s set too low by default. If not, maybe ask your IT team to look into it.
Also, try using a different browser like Edge or Firefox. Chrome sometimes messes with session cookies. Hope this helps!
