Then it appears your upgrade didn’t run correctly as it’s basically saying there is no Queue. It tries to get a Queue by ID if contained in the URL, or tries to get the default Queue from the system settings, or it tries to get the first Queue from the list of Public Queues or Queues tied to the specific Agent.
So check your _queue table to see if you have any queues there. If not you will want to restore from backup and redo the upgrade.
Cheers.
