Default 2018 Radio Stopped Working

Had a very unusual experience on a long trip the other day. Stereo and entertainment system on my 2018 LT Tahoe was working fine until I made a stop.

When I returned and started the truck, I no longer got the message that "wifi" was connected and none of the stereo functions would work. The touchscreen and GPS were working, but none of my radio presets were there and hitting the 'radio' and 'media' button did nothing. The outside temperature was blank on the display and the hands-free phone functions also would not work. I turned the truck off completely and restarted it a couple of times with no success. I also could not play any music through Bluetooth connectivity with my cell phone. This continued for the rest of my 3 hour ride home.

A few hours later, I started up the truck and it has been working fine ever since.

Anyone ever see this before? If there is a problem, I'd love to get it fixed while it is still under warranty. Is there any way to do a diagnostic check of the radio/entertainment module?

THX in advance!
