Bug XR player freezes when another leaves the room.

I'm working on a XR multiplayer (PUN2) project from my studies and can't figure out why my player freezes when someone else leaves the room.

Here is the scenario:
P1 enters the room. P2 joins. When one of the two players leaves the room, the remaining players freeze. Means: They can't move their hands anymore and they can't walk. The head/camera works means they can look around. If now another player enters the room everything is back to normal.

The code below is the logic I use within the rooms. Line 20 has not changed anything. The player disappears when he leaves the room regardless of this line.

Code (CSharp):

1. public class GameManager : MonoBehaviourPunCallbacks
2. {
3.     [SerializeField] private GameObject networkPlayerPrefab;
4.     private GameObject spawnedPlayer; // local Player
5.  
6.     public void LeaveRoom()
7.     {
8.         PhotonNetwork.LeaveRoom();
9.     }
10.  
11.     #region Photon
12.     public override void OnJoinedRoom()
13.     {
14.         spawnedPlayer = PhotonNetwork.Instantiate(networkPlayerPrefab.name, transform.position, Quaternion.identity);
15.     }
16.  
17.     public override void OnLeftRoom()
18.     {
19.         base.OnLeftRoom();
20.         //PhotonNetwork.Destroy(spawnedPlayer);
21.         SceneManager.LoadScene(0);
22.     }
23.  
24.     public override void OnPlayerEnteredRoom(Player newPlayer)
25.     {
26.         base.OnPlayerEnteredRoom(newPlayer);
27.         Debug.LogFormat("Beigetreten {0}", newPlayer.NickName); // Sieht man nicht wenn man selber der Spieler ist
28.     }
29.  
30.     public override void OnPlayerLeftRoom(Player otherPlayer)
31.     {
32.         base.OnPlayerLeftRoom(otherPlayer);
33.         Debug.LogFormat("Verlassen: {0}", otherPlayer.NickName); // Sieht man nicht wenn man selber der Spieler ist
34.     }
35.     #endregion

Has anyone had similar experiences or any idea what the problem might be? I think it could be specifically the XR Toolkit (2.0) scripts.

 

Update: It has nothing to do with Photon. The same thing happens when you create a second XR Origin player offline and destroy it.

 

The problem:
As soon as more than one XR Origin with an Input Action Manager is in the scene and one of them is destroyed, all inputs seem to be disabled.

Solution:
When destroying a player, I now searched for all Input Action Manager scripts in the scene and called "EnableInput()" once.

 

Thank you for the helpful tips!
