Ubuntu 21.10, Pointer froze up, Keyboard unresponsive

Nov Framework DIY, Ubuntu 21.10, defaulted to installing Wayland.
I have a slooooowww wifi connection, and occasionally things seem to freeze (e.g. zoom video) and I have to disconnect / reconnect the wifi to get it back. However, on a recent zoom, the pointer froze and the keyboard also seemed to be inactive – alt tab wouldn’t switch apps so I couldn’t get at a terminal session I had up.
Is anyone else seeing this?
