when starting the session, the error “project is not valid” is returned. What could it be and how to fix it?
Hi Kishiimu,
If you click ‘Show Output Log’, are there any lines in the output log that begin with “Error:” ?
If you see messages about “Found disallowed object type” it’s probably related to this problem.
Welcome to the Forums.
Seems to be a common issue. I believe the short term fix is to use the error code from output log and search items in outliner. Delete offending assets and hope for the best.
