After updating to Ubuntu 21.04 today and even disabling all gnome extensions, I have a problem where if I open Activities, it will not close/exit. I’ve tried using Super again to toggle, or escape, or just running a new program (which usually closes it). Nothing seems to work to fix it from being keyboard basically 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

The same issue for me.
I fixed it by disabling Dash to Panel extension and re-enabled multiple workspaces.
