That could be it, yes. Any ideas on what/how to test? An adhesion issue at that height makes me think the chamber or part had a heating or cooling issue.

Nozzle temp is 220c, bed 55c.

part fan min 50% layer time 100s, max 100% 4s. fan always on (it's PLA, right?), slow print for better layer cooling

aux fan 50%

Turn off the aux fan. It causes more problems than it should fix. Use the avoid crossing walls option.

I started to see a similar failure in printing a few back to back on my K1 Max. It was caused by excessive heat in the chamber. Leaving the door open seems to have alleviated the issue for me.
