Drivers Rear Door Will Not Unlock with Keyfob or button

I have a 2021 Sentra and the drivers side rear door will not open via the fob or by pushing the button from inside the car. Leaving it only operational by manually opening it from the inside.
Any help would be appreciated.

That's almost certainly a bad door lock actuator. You can check it with a test lamp placed across the actuator connector, if the lamp lights for a second or two each time you work the power lock switch, the actuator is bad. If it doesn't, there's a problem with the wiring for that door. It's unlikely to be anything else, the rear door unlock circuits are usually common at the BCM.
