Z Key Bind to Crouch; Not Working But Does For Other Binds

When I bind the Z key to a crouch and then go in the game it does nothing. Now when I bind a new key to Z it does it, then when I bind a new key to crouch it does it. For some weird reason, the bind Z to crouch function seems to not work. I done this on 2 Windows 10 64bit builds (latest version of May 5th 2020) and not sure what to do. I even have gone into the JSON file and bound it to the Z key and still not working neither.

Same problem with 2019 bug.
