Video stream on TV goes dark; audio still playing

Server Version#: 4.143.0
Player Version#:
The title tells the tale- recently this has begun happening while watching video from Plex. If I back out of the video, then resume, it will play fine for a while then go dark again. I can’t see any pattern to it.
I am at a loss as to what settings I should be looking at. I have used my Plex setup for years with no problem but this has recently cropped up. No other stream on my setup has this problem.
Anyone have a clue where I should be looking?

This just started to happen to me as well, using the plex app on a firestick on my tv and the plexmedia server is running in archlinux on my pc. Nothings changed on my end but the issues started about a month ago.

This is also happening with me, specifically when trying to watch on a windows 11 pc in chrome.. it works fine on my Chromecasts and TV Streamers… only Chrome is showing black screen, but audio working. Any ideas?
