It could have twisted on recoil and is now stuck. You'd have to remove the interior panel to view that.

On the really bad side, the seat belt pretensioner could have failed or fired and locked the belt in place. If that's the case, I'd have a mechanic replace it since you can trigger an air bag deployment replacing it yourself.

Take apart the drive box in front of seat track, on both sides with an allen wrench. You can then push the seat to get at the bolts to remove it. My trolley drive motor had bad brushes. I am now looking to replace the motor, if I can find the replacement.

There are plastic gears connecting the track to the seat assembly. Whne one of these strip the seat will only work or move to one side. Infiniti does not sell a simple fix. You are looking at buying an entire seat assembly complete with the module for all the electronics. It will be at a cost of around $950 - $1000. Once that is in, Infiniti must program the seat to the brain of the car, only then can you reset your memory settings.
