ARC unresponsive + crashes on iOS 16

The ARC app on my iPhone X (iOS 16) becomes suddenly unresponsive and crashes. After some time closed, it works again for some time, then starts behaving oddly again.

This happens with both downloaded and streamed content and both over wifi at home as over wireless.

This has started to happen in the last 48hrs. Before that, all worked perfectly.

I’ll add a me too to this - I’m not sure I’d agree it worked perfectly before, but probably a lot better. Slow UI to go with it and frequent crashes and it slows down the rest of the system with it. Multiple seconds to respond from screen off by pressing the home button. iPhone SE 2nd gen.
