Plex add-on not launching

The issue your having seems to be specific to something on your machine and as such would be unlikely to just magically get fixed with an update. Whether the issue is in something having gotten messed up in the operating system or just with the user data of Kodi I don’t know, but if it is the latter then what I posted previously is a quick way to find out and can even be reverted to get you back to where you were before.
