That error is a memory failure.  Try the same reset process, but if it doesn't solve the issue, the result will be the same - the memory on these is soldered to the system board, so if it fails, the entire mainboard needs to be replaced.  
I have a Dell XPS 13. Purchased in 2020.   My daughter was using the device, went to another room, and came back.  The device had shut down but would only turn back up and get stuck on the Dell logo.  Also, the LED on the bottom blinks from 2 white to 2 orange, repeating. I can't seem to get it to do anything other than getting stuck on the Dell logo page. Can someone recommend the next step?  I've tried a hard reboot (holding the power key down) and a few other things read on this site -- Fn key, F3 key, and F12 key.  
Dell XPS 13 Stuck on Dell, but can't shut down NOR push into any diagnostics.
