Perfect, AgentOrange86.. thank you !!
I had the same issue with my 2022 Escalade, it will not start after I used the remote starter.
I started the truck with the remote starter, but it turned off after a couple of minutes. When I tried to start it with the ignition button the truck would not respond, although the lights and dashboard were on. I called OnStar, but they had no clue, they wanted to tow the car to the dealer. After I read this blog, I took Agent's advice and disconnected the battery (just the negative) for 2 seconds, the alarm went off. then reconnected the battery and turned the alarm off (with the remote). The truck started perfectly well and back to normal.. I will not use the remote starter again till I see a fix from GM
