Are you the owner of the team?, Did you check if you have sufficient permissions on the team the project is on (Go to Manage Team and make sure you are either Collaborator,Publisher,Administrator or Owner)
Also make sure you are not logged into a different account
You do not have permission to access cert (whole lot of numbers and letters which i don’t know if i can show) SentryEventId=eab…(again, the same) errors.com.epicgames.creator-portal-backend.operation_forbidden
So weird, Idk what else can be done, Weird how you have perms to load the project in content service but not on the creator portal, last thing I can think is to logout from creator portal and re-login, If that doesn’t fix it which it probably won’t, try asking support if they might be able to fix it. https://www.epicgames.com/help/en-US/c-Category_Fortnite
