Mercedes Benz ML320 Fault Codes P0442 and P0410 - Car Won't Start, Dashboard Lights Only On for Airbags and SRS

I own a Mercedes-Benz ML320 and am experiencing a serious issue. After parking at the store, when I returned, the vehicle would not start. The dashboard lights remain on except for the airbag and SRS indicators. When I remove the key, all lights stay illuminated, and the car does not respond to any starting attempts. Only the two mentioned lights come on—no sound, no movement, no response at all. This issue is occurring after a normal parking session, and I suspect it may be related to fault codes P0442 and P0410, which are associated with the evaporative emission system and catalytic converter performance. I need help diagnosing whether these codes are directly linked to the starting problem or if there's another underlying cause.
