Hevc no longer playing on Vizio smart tv

Server Version#:1.41.9.9961
Player Version#: vizio plex app 5.93.2

After a recent Vizio firmware update, the Plex app for vizio no longer plays x265/hevc content. I hear the audio, but the video is a black screen. A progress bar is available as expected but the entire video content is blank. This is with any direct play or transcoded to x265 content. Before the update, everything played fine. x264 content still plays fine as does network streaming apps using x264 (e.g. plex live tv). Downgrading content to transcode into x264 is not an option as the transcoding quality/bitrate is already sub par.
vizio model d24f-j09, firmware 3.710.30.5-1,
vizios: mtk5583-1.6.970.1-11bf6eb
logs included.
Any help would be appreciated
