Are you using stylix ?

I am using it and got the same Issue. I think this is because stylix changes gnome theme settings and something seems broken on the shell theme settings.

Disabling gnome and gtk target in stylix resolved the issue for me.

In fact, yes! This would explain it, guess we can close this then.
