When pressing Alt, Ctrl or Shift, all the shurtcuts are messed up, and can't use my mouse for the brush. Space bar deosnt work, i cant create clipping mask with alt, i cant select layers with shift.

When I open photoshop, everything works normally, until I press CTRL or shift or Alt, where all my commands stop working.
When I press, for example Ctrl+Z to undo. When I try using Shift to sleect a layer. When i use ALT+TAB to change window.

The errors are. 
Can’t use space bar to move canva. Can’t select more than one layer with Shift. Mouse can’t paint with the brush. Can’t create a clipping mask wiht Alt. Just the few that i tried using.

I had the same mistake a couple days ago, and i solved it by pressing both shift for 5 seconds, and everything was working accordingly. 
I tried using the same trick to “fix it” and it doesnt work.
Last time i uninstalled photoshop 3 times and it didnt work neither.
