Camera Strafe stuck

When I left click, middle click or right click with my mouse to adjust my camera angle to move my character, the camera gets stuck. It moves for a few pixels to the direction I am moving it to then stops completely. I have to re-click for it to move but it repeats the issue.

I have followed all the guides to reset my interface, tried numerous scripts and tried alternative mouse. I play with my Macbook and the issue is also on my trackpad.

Totally out of ideas. The game is unplayable.
