Why did Chromecast stop working on my Android?

I have a Samsung Galaxy Note 10 Plus smartphone and recently I stopped being able to cast anything to my TV nor my speakers, whether YouTube or Hulu or even just sound/music apps like Spotify. It seems I can't connect to either Chromecast video nor audio devices. The devices I can cast to at home do appear on my list of possible casting destinations, but then the content won't display. The attempt to connect from my phone seems to fail every time! Other people at home are able to cast fine. I have already also tried wiping the cache and data storage on the Google Home, Android System Webview, Chrome, and YouTube apps. No improvement!
