Multiple attempts to exempt locally in AV engine exclusion settings unsuccessful. File continues to flag as Plex Media Manager updates library.

After a system restart, this false positive tanked my Plex installation entirely, as it began to flag additional .dll files from the recent update: 1.3.0.3059-6277334.
It needs to be reinstalled presently. I’ve obviously also reported this to the AV vendor, but I thought you guys should know as well, in case there’s anything that can be done in updates with file signatures.
Thanks
