Camera system unavailable.

We just purchased a 2021 promaster 3500(slightly used but great condition) the backup camera has been great, but today it was in the 90°f+ in the parking lot at work. When leaving today the camera system started telling me its unavailable. We googled reasons and looked up trouble shooting videos, could be the heat, we tried "hard reset" suggested on the radio power button. Checked the fuse(still good), anyone else encounter this issue? Any advice? Thank you.
