If anyone has this problem, i put the charger on the battery and everything is good now.

2018 GMC Sierra Double Cab. Got into my truck today and went to started it up my dash, stereo, hvac lights all went out. When you turn the key to acc everything is fine they all light up. Its just when it starts they go out. I'm able to shift and drive fine, I've played with all my grounds and nothing. Batteries 2 months old, mechman alternator 5 months old. Ive have an aftermarket stereo for the past 2 years with zero issues. Last night I cleaned my k@n cabin filter thinking i bumped a wire but all the wires behind the glove box look good. Could it be an ignition switch problem?
