Are you using any software with an overlay? RivaTuner
Which Legend were you playing (if applicable)? All
Which Legends were your squad mates using (if applicable)? N/A
Where did the issue occur? In the Firing Range
Which part of the map or menu were you in? If you don't remember the exact name, please describe the area or what you were trying to do in the menu. I did not doing anything in the menu. I just went in to the Firing Range and tried slide jumping but it just didn't work.
What were you doing when the issue occurred? E.g. respawning a squad mate at a beacon, using an ability, a squad mate left the game: I just opened the game and went in to the Firing Range to warmup.
Did your squad mates also experience the issue? N/A
How many matches had you played in a row before the issue occurred? I was just in the Firing Range. Didn't play any other mode. Prior to that, everything was working fine a week ago. I was able to practice in the Firing Range and play a couple of matches.
When did this happen? (dd.mm.yy hh:mm): May 26, 2023
How often does the bug occur? It just started yesterday, May 26, 2023 and occurred the whole time while i was in the Firing Range. Still the same bug today, May 27, 2023
How severe is your issue? Very severe
What happens when the bug occurs? I just can't crouch jump. For me it's LCTRL + Space Bar. If i assign crouch to other keys, it works fine with Space Bar and vice versa (with jump to other keys and LCTRL).
What should be happening instead? Holding LCTRL should make me crouch and will make me slide if i am sprinting. And if i press Space Bar together with LCTRL, i should be able jump while crouching or slide jump if i was sliding while holding LCTRL then pressing Space Bar
Steps: How can we find the bug ourselves? I honestly don't know. It just happened to me randomly. I tried speaking with other players via Discord regarding this and theirs was working perfectly fine.

Crouch jump was working perfectly fine in my other games too. Already tried repairing Apex Legends, putting my keyboard on a different port, updating Windows10, uninstall/reinstall keyboard driver but none of it fixed it. My keyboard is GMMK Full size.

 EDIT: After following @Aud1cted and @dispendvich suggestion to disable Window's PowerToys' new feature 'Peek', the bug was gone.
