There's no fix yet as far as I'm aware.
The only two "fixes" are either:
1) Set the privacy to maximum (nothing shared). Problem solved but you lose the vast majority of the car's internet features
2) Leave everything on and when the infotainment system freezes, press the emergency button for 1 second, wait around 30-40 seconds, cancel the emergency call that gets initiated (you've got like 7 seconds to do this before you get connected to the emergency services) then all systems should be up and running again
Do note though that with 2) you may occasionally notice random resets (very occasionally) and also being logged out of your account. If that happens, re-enable the privacy settings in the guest account and try to log in again (it may fail otherwise)
