Evidence is pointing to the infotainment computer waiting for something that never happens. By removing as many possible external devices as possible, you might unlock it.

Can you still drive the car? Does the dash still work? I don't even use the center console screen very often, because everything I need, Phone, Radio, Nav, instruments, driver's aids, are all on the dash and HUD.
