Video is not displaying on any channel

Every video I try to play, the audio and captions will appear, but the visuals of the video itself will not display. This is happening across multiple channels and I feel like I’ve tried every solution already said here with no luck. It’s been going on for a minimum of 12 hours and I have no clue what to do at this point. It’s not just channels either, I tried clicking into the daily trivia and I could hear the audio but again nothing displayed. Would appreciate any help to fix this.
