Found a workaround that seems to work. I run these command:
sudo rmmod btusb
sleep 3
sudo modprobe btusb
sleep 5
sudo systemctl restart bluetooth
No powercycle, no system restart necessary so far. Settings/Bluetooth
says either "no Bluetooth" or "airplane mode" when things break.
I'll check syslog again when my problem happens. Are there any other
logs I need to watch?

Are there known problems with Ubuntu 20.04 with regards to Bluetooth
devices?
I recently purchased a Logitech MX Master 3S mouse, and connected the
device to my computer via Bluetooth. This is the first time I have done
this with my computer.
The situation is that the device works fine for about a day. The next
morning, the computer does not respond to mouse movement or clicks. When
I reboot the computer, it all start working properly again.
(The mouse also came with a USB receiver, which I have been able to make
work, but that's a problem for another time.)
I checked syslog, and didn't find anything enlightening.
I followed instructions I found for Ubuntu 16, including reinstalling
the software, and no change.
My reason for buying this mouse is my various logitech mice, after a
long time of use, start double-clicking by themselves and misbehave when
doing click-and-drag operations. The new mouse allegedly has optical
switches, which should not have this auto-double-click going forward.
(Yes, I still keep the original flaky mouse handy for when the new one
stops working. So far I've been able to avoid nasty power-downs or
hardware resets.)
