Extruder gears not gripping the filament

I am printing on an Elegoo Neptune 4 and my problem is that in theearly stages of my print, exteuder gear moves but filament is not fed into the extruder and doesn't move one bit. I opened it up and found out that the filament was broken inside the print head and fixed it but that happened again several more times and the filament had not been broken. It was just not being fed into the extruder anymore despite the gears turning.

Any idea what the problem can be?
