2d Physics collision problem

I have a prop that has enabled physics, and when I jump on this prop it gets stuck into the ground, the weight on the prop is 5kg ccd is enabled, and the weight on my character is 1kg. I have no clue what it is, and the collision on everything is fine because when it just falls a for a second it doesn’t get stuck but when it falls for 2 seconds or so it glitches into the ground. Any suggestions on this, in the images the gameboy is the prop and my character is on top of it. I feel like if the gravity was the same for both of them it would be fine because then it would be hard to jump on it in mid air but the gameboy falls slower.
