Can't move mouse and press keys simultaneously

Hi all! I have an M2 2022 MacBook Air, with the Asahi 42 Plasma Spin, and I am struggling to play first-person shooter games, as when a button on the keyboard is pressed, I can’t move my mouse.

This is really annoying as it means I have to stand still to aim.

How could I fix this?
Cheers, Max

I feel a bit stupid asking here as I found it by myself literally 3 minutes later while looking around settings.

KDE Settings > Mouse & Trackpad > Disable while typing
Turn it off. Weird trackpad issue.
