Additional context

After rebooting I switched to another TTY and checked the status of sddm:

~ systemctl status sddm

Looks like something is wrong with the display number.

Here how it looks in the hybrid mode, when everything works fine:

And here is the logs of switching to nvidia:

Turns out it was a driver issue. I completely removed all nvidia and nouveau packages and after that installed nvidia driver one more time. After that everything works as expected.
