Game breaks after instantiating particle system

After I instantiate particle system my game starts to lag,duplicate objects,camera stops rotating on X axis,every time I press space it plays sound,teleports me and console is filled with messages like “There are 64 audio listeners”
Here is the code:

`using Photon.Pun;
using Photon.Realtime;

using UnityEngine;
using UnityEngine.UI;

For some reason code here doesnt have spaces but heres whats causing the problem
ParticleSystem particleINS = Instantiate(particle, jumpPos);
