Game bugs in Editor but not in the build


I am working on a 2D game and I have a problem. Everything was working fine but I don’t know why since today appeared some issues.

Whenever I play the game in the Editor it has a lot of bugs. When I first start the game all objects move very fast for about one second then in runs normal. Another problem is whenever I jump with my character he jumps lower than it should and sometimes he jumps very, very high.

The build works perfect. I am using deltaTime for everything.

EDIT: Added video - YouTube

Physics should always be handled in FixedUpdate
