Black screen and no sound when streaming from Steam Deck to LG TV

Hi everyone,

I've been using a Decky Sunshine on Steam Deck to Moonlight on LG TV setup for the past few months with mostly no issues.

Recently the Moonlight app disappeared from the TV (probably due to Developer Mode shenanigans). I tried to reinstall Moonlight using the WebOS Manager but now whenever I pair it to my Steam Deck and hit Resume Streaming, Moonlight seems to freeze. The screen is black and there's no sound from either device, although the game is displayed from the Steam Deck and can be played there (albeit with no sound).

I also cannot interact with Moonlight in any way (e.g hitting the back button on the remote). If I hit Home and revisit Moonlight, it'll show "Disconnecting..." but not actually disconnect. The only way to restore sound to the Deck is to turn off the TV using the Power button.

Has anyone else run into a similar problem? Any fixes?
