Saw a guide on how to deal with vehicles' info-screen systems when they blacked out or froze. It's a treatment for the symptom, not the underlying cause; they recommend that you take it to the dealer if it happens again, or even just once, to be sure everything is good to go. Anyway, for GM:
Mylink/Intellilink (2014-2016)
• Press the Home and Fast Forward buttons for at least 10 seconds
GM infotainment (2017-2019)
• Press the Onstar call button, then hang up.
Hopefully, this is useful to someone.
