What causes this bounce when walking over something?

What causes this Imgur: The magic of the Internet to happen? And what could I do to prevent it? I’m not sure if it’s code related or like physics related, but yeah can’t seem to escape it whenever I try to make movement.

It’s related to whatever character controller you’re using, it’s not Physics since Physics are realistic and an object wouldn’t stay in the air for any amount of time.

I can recommend Unity’s official character controller Kickstart your game with First and Third Person Controllers! - Code Monkey
