I have just installed Unity and I can’t create any new projects. I get this message when ever I try to start a new project and I don’t know what to do.
Does your Windows user account have admin privileges? It’s possible that Unity Hub doesn’t have access to the directory you’re trying to write to. Try closing the Hub entirely (make sure you right click it in the task bar and exit) and run it again as Administrator to see if that resolves it.
Actually… now that I’m looking at where you’re trying to create the project, that might just be a protected directory that apps can’t write to. Try creating it in a different location.
Check that you have sufficient space. Recent releases have been creating projects around a gigabyte.
