After updating to Ubuntu 21.04 today and even disabling all gnome extensions, I have a problem where it will not close/exit if I open Activities. I've tried using Super again to toggle, escape, or run a new program (which usually closes it). Nothing seems to work to fix it from being keyboard useless then. It happens every time it opens. This issue is critical as once Activities is stuck open, the user cannot interact with any windows, and they must log out
P.S this problem is no more in Ubuntu 22.04 until now.
