Yes, that sounds like the same issue. Right now i'm running Creality's release from their hompage. Not a perfect solution as babystep Z is only 0.1 increments and i need to reverse the filament runout sensor's activated position which isn't possible without the source code. (The source code offereded on their own page didn't work correctly either)

I have the same issue with marlin 2.1.x bugfix. I just downloaded it this morning, installed it on 6 machines.

If power loss is disabled absolutely everything works, but as soon as I enable power loss recovery, it will auto home all, heat up the bed and nozzle, do the purge line on far left of build plate, attempt the very first layer, and then reboots, reheats, and keeps retrying...

Funny thing is that for some reason my printers print so much better with Marlin 2.1, so I really need power loss to work as well.
