[arch-general] Can't change tty, any ideas?

Hey hey,
I'm running on a 5.4.24-rt15-1-rt #1 SMP PREEMPT_RT kernel and since I've been 
back - after a day - and rebooted my machine, Ican't change ttys anymore.

I checked the keyboard with showkey, both alt and the f-keys come through. No 
job is overtaxing the CPU. It's almost down to 0-2% CPU usage.

The keyboard is connected via USB, I had PS/2 keyboard issues a long time ago 
so switched. The HUB is working, other devices - including my braille display 
- work flawlessly. I'm currently typing this mail on my system.

I know, this probably isn't strictly a matter for this list, but it is a good 
pool of knowledgeable and helpful people.

So, can anyone suggest probable causes, methods to hunt the bug?

TIA and best wishes,
