The problem that the Megascans Library folder path isn't getting saved during installation still exists:
Today I setup an empty drive with a new operating system and a fresh installation of UE 5.0.1 and this happens again. As said in upper mentioned post, it's fixable by clicking the Account Icon and open "Preferences". Then set the Megascan Library path correctly (the path you entered during installation). The save button was very responsive! I closed the pref window again and clicked on the "x" of the little popup that says the background service couldnt get started. then opened preferences again, adjusted path and the save button worked. just try around a little ;)
