Input.GetKey acting weird

Unity Engine
1

Hello,I encountered a strange problem with Input.GetKey…
I put Input.GetKey into update. If the key is pressed, it sets a bool to true, if not it sets the bool too false. I tested it by printing the result of the if statement to the console, but it acts really weird.
Once the button is pressed it goes like this:
True
False
False
True
False
True

It seems to be completly random. Ive no clue. As long as the button is pressed leftward should be true, but its like i let go of the button for a millisecond…

Would be nice if someone could help me,
thanks in advance, Fabian

double click the debug.log that says false and see if it goes to that Debug.Log(leftward);

If it does, create a new script with just the If(Input.GetKey(KeyCode.A)) and see if it still shows it being false and true.

After changing my keyboard twice, it worked.
Thanks for your help anyways!
