This error happens in line 51:

PhotonApplicationId = PhotonNetwork.PhotonServerSettings.AppID

Therefore, I am suspecting that the AppID in PhotonServerSettings is not properly configured, could you please take a look it to see if that's the case? If that's the case, maybe you should try resetting the PUN setup following this sectionl: Setting up Unity Project
