I can't save a scene in the tutorial project.

I saved my tutorial project in my user folder in the C drive. It has an ‘Assets’ folder, but I can’t save my scene into it as “The scene needs to be saved inside the Assets folder of your project”.

When I try to save the scene, the Unity editor automatically opens up the AppData folder (which I can’t normally access manually) and under Temps there is also an Assets folder, which I can’t save to, as I get the same notification.
I’ve read threads from people with the same problem, but I’m still a bit confused.

I seem to have fixed it by ignoring the App Data folder altogether and just opening the tutorial project folder in the Unity Hub. Then I was able to save my scene into the ‘Assets’ in that project folder. Don’t know how this worked, but someone may be able to enlighten me.
