-update windows
-Update to the latest version of Plex
-Delete all windows updates
-Downgrade various older versions of Plex
-Reinstall windows without updating
All tests lead to the same result
Around 10pm - 11pm Plex stops working however the service is still running.
I have to restart the process manually for it to work again.
I am currently using version 1.31.1.6733 where I have given up testing
I have seen other threads related to the same problem but with no apparent solution.
