[SOLVED BY ME] Why is the D key not moving my character?

Apparently the D key does not move me, this is only for my game, it does not work both in studio and the real game, help me please. (I did not add any scripts restricting movement, and I didn't do ANY scripting with the D key, I have used the userinputservice but only for the Z key, the D key works in chat but doesn't move the character)
