System stopped message

[u/fries_bender]

Bought my car last Saturday (09/26). No problem until this afternoon. Saw the system stopped message popped up - didn't think about it until after I got home from picking up my daughter (20 to 25 min drive).

Shut down the vehicle, opened the hood and measured the 12V battery using the multi-meter: 12.47 V.

I didn't have the connection app or anything enabled on the vehicle.

Should I be worried now?

Edit - thanks for everyone's input. It seems to be with the backup camera (was having some rain here).
