Help me please if you have experienced this or know what to do. My Bambu Lab A1 combo 3D printer is unloading and loading filament endlessly before printing, or it is unloading and then loading it back, then it starts extruding filament, stops, and says that the nozzle is clogged, but I am sure that it is not clogged because I cleaned the nozzle before printing, and if I manually force the printer to start extrusion, it easily extrudes filament. help please.

Please help me solve the problem with the application. It doesn't want to start printing. It gives an error.Original model was switched to draft, deleted, taken down, or set to Private.
