I've found a previous thread that is now locked but is about the same issue:
Since Android 12 update, every time I cast a video from the YouTube app on my Pixel 5 to Chromecast, the video disconnects after a few second or minutes.
Reset my router
Cast from incognito mode on the YouTube app.
I have not uninstalled the home app because I'm afraid all the data will be lost.
What more can I do?
