Hey @fael097!
Question: When you copy the project into the workspace (also do you have a p4ignore.txt file set up?), do you start the project using the .uproject file in the workspace? Or do you use the launcher? The first time you start it after moving, it needs to be launched from the .uproject.
Then you should be able to attach it through UE5 to Perforce, as long as you have your P4V logged in.
If you do not have your p4ignore.txt set up, I implore you to do that so you don’t add unnecessary files to your depot.
Also once it’s there make sure to make your .uproject file and DefaultSettings.ini writable. Not a problem for you yet but definitely something to do once it’s on there.
Believe me, I’m no stranger to Perforce antics. There’s a reason there’s usually dedicated staff to run it at most companies.
