PMS Update v1.4.3.3433 has broken Watch Later, anyone else?

Just updated to Plex Media Server v1.4.3.3433 on Windows 10 Pro x64

Since updating, nothing will play from watch later, using plexweb, plex for windows app, openpht.

i cleared out all the Watch Later videos, added a new one via Plex IT! which i verified play fine on youtube, no difference

anyone else?

edit: GIF added from plexweb showing the error.

May we have your full logs, immediately after recreating this event please? (Settings - Server - Help - Download Logs). You may attach the ZIP file here.

maybe it was a false alarm, today watch later has started working again, same video as in GIF above.

if it happens again on this version i will post full logs to this thread

thanks for your reply.
