Nothing plays on tv

And you've also tried running the tray app as admin?  It still looks like there are a bunch of permission issues.

And to clarify thunderbolt's suggestion, you should be granting YOUR user full access to Jellyfin's programdata folder.

Yes I right clicked the desktop icon and selected Run as administrator.

I granted access to all users. Everything in the security tab. Everything has full control in Jellyfin's programdata folder and the full folder of the app itself too. 
I even disabled the windows firewall to see if that was the issue. But it made no difference.
