Camera issue, gets stuck when holding the right button and moving the camera?

This appeared random, I checked all scripts if they did something to the camera and found nothing.

When moving the camera and when you then hold the right button it will keep turning for example : You use the left arrow to move ur camera and hold the right button at that moment it will keep on moving left even when u stop holding the right button until u stop holding it and press the left arrow again.

I'm very confused by this since I've never seen this before and can't find posts about the same problem.

Sorry if it is a bit understandable, Thanks in advance
