Character Controller collision with Rigidbody problem

My Player uses the Character Controller to move around, and the Tree has a Rigidbody with a box collider.

When I wait for the Tree to fall to the ground Player cannot move it (which is intended).

But as the Tree falls and you bump into it, the Tree gets pushed rather quickly and feels like it weighs only 1 gram, any thoughts on why this is happening?

I’ll give a bunch of suggestions:

  • Increase the falling tree’s rigidbody mass generously.
  • Changing the physics layer when it’s falling so it no long interacts with the player (then change it back when it’s on the ground and set its rigidbody type to static).
  • Prevent player movement if its next position overlaps with the tree’s collider.

Thanks for the reply @MSavioti after
some tweaking I managed to fix the
problem by disabling players collision
detection while tree is falling. was
as simple as this haha

private void TreeMovementCheck()
    {
        if (!treeLogRigid.IsSleeping())
        {
            playerController.characterController.detectCollision = false;
        }
        if (treeLogRigid.IsSleeping())
        {
            playerController.characterController.detectCollisions = true;
        }
    }
