Is this using the print profile I provided or using the STL files? Can i ask what filaments you are using? I have printed several successfully using the print profile i uploaded. I'm not sure why you're having so many separations! I would try doing flow calibrations on your filaments to make sure they're working properly.

Bambu Matt filament and the original Bambu profile. calibrated flow I use the option open on Bambu slicer
