Logitech Options won't let me change the "Keystroke assignment" assigned to a mouse button anymore. I just get a sad error noise every time I try to set one.
Strangely, there are already keystroke assignments set for the mouse buttons on one of my Logitech mice. (I set them a long time ago.) They appear in the Logitech Options app and those assignments still work. But I cannot change them.
This is on Catalina, and I have Logitech Options and Logitech Options Daemon enabled under Security & Privacy => Accessibility and Security & Privacy => Input Monitoring.
Logitech Options used to work fine for me, but it stopped working at some point, and now no amounting of fiddling seems able to make it work properly again.
