Something catching alt+1 and alt+0

Hey, i use kde plasma on linux mint.

I wanted to configure a few keybinds in a software, but something catching the alt+1 and alt+0 keybinds, before they reach the software. Seemingly it does nothing.

If i configure an action for these buttons (eg.: open the calculator), then delete these binds, then these keybinds reach the desired software, for like 5-10 minutes. After that, it does nothing again. (The numbers and the alt buttons works perfectly in every other scenario)

I tried it in a different DE (cinnamon) and these keybinds working perfectly. So i think KDE catching it somewhere.

My version numbers:
KDE plasma version: 5.27.12
KDE framework version: 5.115.0
qt: 5.15.13
linux mint: 22.2

and im on X11.
