Win 11 Pro Smart App Control blocking all the Plex Codecs

Server Version#: 1.43.0.10467

Just updated Plex Server to 1.43.0.10467 and suddenly Windows 11 Pro 26200.7628 Smart App Control is blocking all of the codecs, making Plex unusable. I received an error message that said something along the lines that it could determine who published them. WTH.
