Plex crashes after latest Windows update

Server Version#: 1.16.5.1554
Player Version#: Web Client 3.108.2

Since latest Windows Update Plex crashes when trying to play any HEVC file with hardware acceleration checked. File plays ok with hardware acceleration unchecked.

Windows 10 Pro 64-bit
Version 1903
OS build 18362.356

Intel Core i3-7100 CPU @3.90GHz

Any idea which windows update (kb)? I have had my Win Updates turned off for some time now, never have had any issues at all w/ PMS crashing yet. It’s dedicated to PMS so i dont care about the Win Updates.

It was Feature Update 1903 that broke it. I just rolled back Windows to version 1803 and hardware transcoding is working fine again.

Settings > Update & Security > Recovery

If you upgrade to 1903 and replace mfplat.dll file with the one in the 1803 or 1703 then it solves the crash too.
