From to Rotation Glitching My Character Controller

So I am making a character controller which uses Quaternion.FromToRotation to align the player with the gravity center in this piece of code:

this_body.transform.rotation *= Quaternion.FromToRotation(this_body.transform.up,gravity_up);

And when I am on certain parts of the sphere planet it starts flipping out everywhere, like in this video, and I don't know how to remedy this, although maybe the gravity implementation could be the problem, or the character controller, although I think using relative force should not mess with it.

Gravity Implementation:

float distance = direction.magnitude;
float forceMagnitude = G * (obj.GetComponent<MultiAttractor>().rb.mass * rb.mass) / Mathf.Pow(distance, 2);
Vector3 force = direction.normalized * forceMagnitude;
rb.AddForce(force);

My character controller script is a bit long so I don't think I should bore you with it, although if needed I could provide it.

This is for anyone who is having issues with using Quaternion.FromToRotation with a rigid body character controller:

I did not dig much into your problem but you are manipulating the rotation directly in the code with Quaternion.FromToRotation and also with physics. I think you need to stick to one of the two, because using both might lead to unexpected behaviours. If you introduce a "raw" rotation modification, the physics engine deals with it. – rustyBucketBay

Basically just use physics rotation like Rigidbody.rotation for rotating things like Transform.Rotate or if you want to rotate physics objects like you are adding force, but instead of moving things it rotates things, then use Rigidbody.AddTorque, or just don't use any physics rotations with other types of rotation as it can cause problems, as stated by rustyBucketBay
