I think that plex support is somewhat aware that some are having an issue:
https://forums.plex.tv/t/browse-in-livetv-tab-reports-error/920628/14
My suggestion is that each person with this issue start a new post on here. Be very specific on what the issue is. The title should be very specific. Like - Updating from 1.41.7xxxx to 1.41.8.xxxx caused this problem.
Follow all the guidelines: https://forums.plex.tv/t/help-us-help-you-how-to-provide-logs-to-get-your-problems-identified-and-hopefully-resolved/672904
Be sure to list your OS and version. Your current pms version. Which players work. Which players don’t. And their version.
Most important: Post your Logs. Full Logs.
