There is no errors with mv now in your logs. Only error I see its Could not pass event PlayerJoinEvent to StaffPlus which means a possible issue with your StaffPlus plugin then. I don't see any issue with MV.

I suppose things you can try:

• Get the latest paper /spigot build
• start your server with only mv installed
