PUN is being incredibly slow in builds

Hello! I'm currently creating a very simple pong clone with multiplayer, every aspect of the game works fine except for the multiplayer part. Creating a room and everything is fine in the editor, but as soon as I make a build and run it everything is 20 times slower, and it doesn't even seem to be able to create a room. And my internet stops working aswell, when i try the build.

I don't know if this code is even close to correct (I would appreciate help with that to)

     using UnityEngine;
     using System.Collections;
     
     public class ConnectRandom : MonoBehaviour {
     
         // Use this for initialization
         public float spawnpos;
         string curstage;
         private const string roomName = "Room";
         RoomInfo[] roominfo;
     
         private void Awake(){
             PhotonNetwork.logLevel = PhotonLogLevel.Full;
             Debug.Log("Awake!");
             if(!PhotonNetwork.connected){
                 PhotonNetwork.ConnectUsingSettings("1.0");
                 curstage = "Connecting...";
                 Debug.Log("Connecting...");
             }
         }
         void OnJoinedLobby(){
             Debug.Log("Joined the Lobby...");
         //    JoinGame ();
             PhotonNetwork.JoinRandomRoom();
         }
     
         void OnPhotonRandomJoinFailed(){
             Debug.Log("Couldn't join a random room");
             curstage = "Random join failed";
             RoomInfo[] rinfo = PhotonNetwork.GetRoomList();
             for(int i = 0; i < rinfo.Length; i++)
                 Debug.Log(rinfo[0]);
     
             curstage = "Creating a room";
             Debug.Log("Creating a room!");
             PhotonNetwork.CreateRoom(null); // Doesn't move past this point as far as I can tell
         }
     
         void OnPhotonCreateGameFailed(){
             curstage = "Failed to create game";
             Debug.Log("Failed to create a game!");
         }
         void OnJoinedRoom(){
             if(PhotonNetwork.isMasterClient)
                 PhotonNetwork.room.SetCustomProperties(new ExitGames.Client.Photon.Hashtable(){{"ScoreServer", 0}, {"ScoreClient", 0}});
             if(PhotonNetwork.isMasterClient)
                 spawnpos *= -1f;
             Vector3 spawnvec = new Vector3(spawnpos, 0f, 0f);
             GameObject go = (GameObject)PhotonNetwork.Instantiate("Playerone", spawnvec, Quaternion.identity, 0);
             go.GetComponent<Paddlemove>().enabled = true;
             Debug.Log ("Joined a Game!");
             curstage = "Joined game";
             Debug.Log((int)PhotonNetwork.room.customProperties["ScoreServer"] + " " + (int)PhotonNetwork.room.customProperties["ScoreClient"]);
         }
     
         void OnCreateRoom(){
             curstage = "Created a room";
             Debug.Log("Created a Room!");
         }
     
         void OnGUI(){
             GUI.Label(new Rect(0f,0f,100f,20f), curstage);
         }
     }
