I had a similar issue and it was a bad stepper motor. The bearings on these are just wide open and a bunch of filament dust had worked it’s way into them. Turning the motor shaft by hand you could feel it get tight at certain points in the rotation. I just swapped in a new motor but you may be able to clean it out if you want to save the $9.

I would start by disassembling the extruder and see if the motor rotates properly. If it doesn’t, then check wiring from driver to motor. if wiring is OK then it’s probably the driver that’s dead.
If it does move properly when disassembled, check shaft that connects it to the gears.
