This problem was fixed earlier today.
There was a delayed impact for this bug because of long expiry on cache for a specific url. Only users with the Cloudflare cache expiring started to experience the problem due to incorrectly formed data for tmdb access .
The fix was deployed about 4 hours ago and Cloudflare cache cleared down
A Plex Media Server restart is needed as it caches the data in the session and the bad data caused by this bug would only get replaced by a restart
