Try cut the filament end on 45* before loading in the AMS and try again
Check if the PTFE tube is installed well and relatively good angle to the extruder the path inside may be not well organized
If that does not work there are some prints for Bambu to solve this
I personally have not experienced this issue, but seen somewhere people complaining and printing the improved part like:
