A350 snapmaker 2.0
quick swap
brace kit
Luban 4.13.0
firmware1.2.3 current
I would first try re-installing Luban, and re-installing the machine firmware via USB.
software / firmware refresh made no change to the issue.
Extruder calibration was already addressed.

I think your thermistor is faulty and causes a heat runaway error.
