Flashforge Creator Pro extuder motor trouble, need expert help

Hello there,
I'm a new member here but I visited this forum a while ago when I first bought my Flashforge Creator Pro.
I used my printer regularly to print simple things for my work, but a few weeks ago the extruder motor (most probably) sound a bit strange when I tried to load filament, and also with burnt smell while no filament on it.
I post this with a video with sound also, I really need help on some input about what's wrong this my machine, should I replace some parts or just need to tweak something inside.
I'm not very familiar with soldering and all those thing but I can get some help with that. The problem here is we can't bring the broken 3D printing machine to a repair shop since there isn't one.
Any help is greatly appreciate it.
Thank you for all who took time to read this post and answer it.

Sincerely,
Lukman

might need a new stepper motor.
Pretty easy to change.

Not sure what voltage you need though.
It's a standard nema 17 motor. And no soldering required. Just a couple bolts and a plug. Stripped mine out recently and replaced with plastic model :-)
