Answer 1

In general, it turned out to reproduce the problem)
How did I manage to win.
Go to Finder settings > Sidebar > Check all checkboxes in the favorites bar.
With such settings, everything is like yours, and if you just open the Finder, then there are favorites (exactly as described by you)
And if so, then "Favorites" appeared.
Even if you add Icloud Drive, it also appears - it is not necessary to put all the checkboxes.
Well, restart the Finder through the terminal just in case. Here is the killall Finder command
I hope it helped
PS You can also remove all the daws first, and then put them again.

Answer 2

Fixed the problem in a similar way - periodically appears again.

Answer 3

In general, exactly the same problem, only a reboot helps, maybe someone knows a more long-term solution?

Answer 4

It also helps only through a reboot, but at some stage the favorites fall off. And the most unpleasant thing is that the links in the programs in the Open Recent menu disappear. You have to either reboot or look for recently used pens. Which is very pleasing..
