SUMMARY

Some background that is connected to the issue:
Due to Nvidia driver issues, when booting my system, sometimes my Valve Index VR headset gets initialized in an unusable state where it isn't recognized by SteamVR. To re-initialize it into a usable state I have to unplug it's power cable and then plug it back in.
This is also discussed here: https://bugs.kde.org/show_bug.cgi?id=487938

Now my "real" issue:
Whenever I plug back in the VR headset's power cable to re-initialize it, the screen freezes and no mouse/keyboard inputs are registered anymore. I also can't switch to a TTY (e.g. Ctrl+alt+F3).
If I leave a youtube video playing before plugging in the headset, it's sound continues playing but the screen including the video freezes. Pausing the video doesn't work because inputs aren't registered anymore.
If I unplug the VR headset's power cable the screen unfreezes and everything works again.

ADDITIONAL INFORMATION:
- I can hear KDE's "device connected" jingle twice before the screen locks up.
- ssh to the PC after the freeze works fine and it responds to commands.
- I found the following errors being spammed into journalctl multiple times per second while the system is locked up:
Sep 15 11:00:08 linuxjoni04 kwin_wayland[1174]: kwin_scene_opengl: 0x502: GL_INVALID_OPERATION error generated. <image> and <target> are incompatible

(see attached journalctl --boot 0 for full journal)


STEPS TO REPRODUCE
1. Boot PC & Log in
2. Plug in VR headset
3. Try to move mouse or type anything on keyboard

OBSERVED RESULT
-> Screen freezes and no inputs are registered anymore

EXPECTED RESULT
-> Being able to continue using the PC with the headset plugged in
