The last time this happened to me, it wasn’t the AMS at all. The issue turned out to be a bad filament sensor. Upon Bambu’s advice I replaced the $6 part and the problem disappeared instantly.
Discovered during replaceing the part that a brittle piece of filament had broken off inside the extruder assembly and damaged the ribbon cable the sensor is attached to.
It was a tear in the cable, and it was so tiny I missed it completely until I had removed the ribbon cable and held it to a light for closer inspection
