I would suspect that since you're losing your dash cluster display and potentially other electronic features, the error message "Vehicle Network Communications Error" indicates a problem in your CAN bus in the truck. It's the computer network bus for the ECU to all the components.
It doesn't sound like some kind of radio communications error, to me. I can't believe a dealership cannot run an ECU troubleshooting routine or scripted fail-check test to detect any CAN bus anomalies. You might want to quiz a different dealer.

2025 Ford Explorer Network Vehicle Connection Error
I get this error after driving about an hour and a half. My whole dash goes blank, i cant see my speedometer, radio goes off,ac goes off, check engine light comes on etc. I have taken it to the dealership 3x already and they have been unable to fix it. I have only had my car for 5 months and no one knows how to fix it. I need help! I am thinking of starting the Ford Buyback program bc no dealership can fix it! Help
