Hello, I'm Cam.
Can I get your first name please?
Does the door close electronically on its own or no?
If it will not move at all on its own but works proper when manually operated, it's likely the lift gate assembly. There is a plastic gear inside that fails and causes exactly what you describe. Unfortunately the gear is not available on its own but rather it includes the motor and gear assembly. It's not bad to change and is about 500$ for the part.
