Symptoms

Stylus taps are registered as well as button presses (on the last cursor position). Cursor doesn't change position.
"Test tablet" in "Drwaing Tablet" KDE settings only displays Stylus release events.
X11 works.
Finger touch still works.

Solution

Rename or delete ~/.config/kcminputrc, or remove config section related to "Pen" (not tested). Deleting the config resets other mouse pointer settings like speed, device enabled/disabled and calibrations.
Then log out and log back in.

Precursor

Testing pen in "Test tablet" section.

Other attempted fixes

Log out and back in - Fail
Reboot - Fail
Moving cursor on login screen and during login process - Fail
Insert and remove pen again - Fail
Shutdown and disconnect battery (in UEFI) - Fail
Removing kcminputrc after diffing with Timeshift snapshot and filtering for interesting files with grep - Pass

I had trouble with my stylus for a while now, it seems to not "click" anymore, but it used to work a year or so ago.

Maybe thats the solution! Thanks for sharing, I'll try it out.
