#player moving and rotating without pressing button

Hey all,

I already looked through the forum but couldn't find the right solution for my issue with my player movement.
If I hit play, my player capsule moves correctly in the beginning but after a while (10-60sec) and more wasd input the capsule starts spinning around the y-axes(the other axes are frozen under the rigidbody constraints) and changes position slowly, without any keyboard input.

I checked the input manager(working with macOS 12.6.1 and MacBook pro-2015), gravity and dead options, but that did not help. My Script is attached.

I would really appreciate it if someone could help me find the solution.
best, jakob
unity version 2020.3.26f1

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class CapsulePlayerScript : MonoBehaviour
{
public float turnSpeed = 20f;
public float m_Speed = 0.5f;

Rigidbody m_Rigidbody;
Quaternion m_Rotation = Quaternion.identity;

private GameMaster gm;

void Start()
{
    m_Rigidbody = GetComponent<Rigidbody>();

    gm = GameObject.FindGameObjectWithTag("GM").GetComponent<GameMaster>();
    transform.position = gm.lastCheckPointPos;
}

void FixedUpdate()
{
    //Movement
    Vector3 m_Input = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
    m_Input.Normalize();
    m_Rigidbody.MovePosition(transform.position + m_Input * m_Speed * Time.fixedDeltaTime);

    //Rotation
    Vector3 desiredForward = Vector3.RotateTowards (transform.forward, m_Input, turnSpeed * Time.deltaTime, 0f);
    m_Rotation = Quaternion.LookRotation (desiredForward);
    m_Rigidbody.MoveRotation(m_Rotation);
}

void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
    }
}

}

    //Rotation
        Vector3 desiredForward = Vector3.RotateTowards (transform.forward, m_Input, turnSpeed * Time.deltaTime, 0f);
        m_Rotation = Quaternion.LookRotation (desiredForward);
        m_Rigidbody.MoveRotation(m_Rotation);

This 3 line look super suspicious .

If constraints don't work, you can always set the angular velocity to zero in FixedUpdate()
