K1 Max stopped while printing with blinking lights

OK guys, while printing on my K1 Max, the machine stopped. Exported log. Tried everything (unplugged, checked for loose connections, disabled filament ending detector, etc., nothing works. Seems it’s not communicating with extruder (2001 error, I know what the error is). When I start another print, it does the alignment thing then just won’t go any further and just pauses. Any tips. No warranty.
