After having this exact issue, I researched Reddit and found the solution. It was simply disconnecting and reconnecting the Arc connection which was confusing the Bluetooth connection. I then remembered previously showing my brother what the unplugged Optical (Arc) sound cable connection looked like when powered, which is like a red laser, that was connected to my sound bar and that's when i probably confused the bluetooth connection after plugging it back in.
So I then tried unplugging the optical sound cable and plugging it back in, and so far the problem is solved. I haven't tested HDMI Arc connections because I don't use that connection anymore and therefore haven't tested it.
