Zoom for Mac 5.14.5 update nukes prefs on launch

[brunerd_estc]

Heads up: It seems installing the IT pkg version 5.14.5 for Mac erases the local prefs and database on app launch.

The prefs stay in place after installation but upon launch it will erase the prefs, require SSO sign in again and to the consternation of users, erases all their locally stored backgrounds.

~/Library/Application\ Support/zoom.us/data/zoomus.enc.db
~/Library/Preferences/ZoomChat.plist

The notes mention "Security enhancements" so I guess this falls under that, but kind of a bummer for folks with prolific background libraries.
