Cant click or scroll anything

Cant click or scroll anything.

So I was trying to make my fingerprint sensor work but after a reboot I can't click or scroll on anything except the login screen. The only package I have installed immediately before that reboot was python-validity (because FPrint does not support my sensor). I uninstalled it, but the problem still happens after logging in. (With touchpad AND external mouse)

Keyboard including Keyboard navigation works fine.

So what next?

Edit: Clicking on any icon in the dock also works (GNOME 40)

How to provide good information
If don’t wanna read for now, start to look into man journalctl and if still no hints from journalctl logs than may be now it the case to read.
