Garmin G1000 PFD suddenly not working

Does anyone know why, all of sudden, my C172 PFD looks like this? I already on the sky but the pfd saying i’m still on the ground (300ft). You can also see the airspeed also not updating, also can’t see my current altitude. Pitot heat is on.

Autopilot works fine though, but since no airspeed and altitude, if i dont manually pitch down the AP it will continue to climb.

Also also the game complaints that i dont have enough fuel mixture even though i already set the fuel mixture to 100.
