I have fixed the issue What you have to do is download or open Steam.Then download and install VRChat.When Easy Anti Cheat is asking do you want this app to make changes to your device then choose the options yes!When you are in VRChat the game.Try again to play MCOC on your pc.Hope this will work for you.
