This is just a guess, but did you check the 12V battery? My 500e had a 12V battery go out in the middle of the night and did something similar. Then, my 2017 Bolt did the same thing while I was at work. Both cars would give me a ton of errors and not turn on. 2018-2023 is about 5 years, close to the age of both my 12V batteries when they died on me. I am now going to be replacing the batteries every 3 years to prevent me from getting stranded somewhere like the time with my Bolt. Neither car warned me the 12V batteries were going bad, it just happened.
