Prevent character from pushing an object it's standing on?

It’s kind of a funny bug, but when standing on a physics object, a character can defy the Newton’s third law and push it in the direction it’s going.
Still, I’d like to fix this, and I couldn’t find any setting in the physics tab that might handle this. I assume I’d need to manually detect whether a character is standing in a physics object and apply counter force, or are there built in ways?

I remember there was a way to modify the object’s weight, if you set it to an incredible high weight it shouldn’t move

But I want it to move… Just not like this
