PLEX desktop player for Windows is still presenting a blank screen yet playing audio on all video, this has been reported before (See https://forums.plex.tv/t/black-screen-on-all-media-after-updating-to-1-42-1/783707/38 & https://forums.plex.tv/t/help-no-image-while-playing-a-video-with-plex-only-sound/788471) but had no official response or fix in the last few releases.
The last working version (that I know of) is Plex-1.41.0.2876-e960c9ca-x86_64.exe.
Mods, could you say if being looked at? Thanks
