No photo.

I think the locking pin is jammed or corroded.

Check fuse 20 to see if that is blown - usual fault is the actuator mechanism is seized and will need cleaning up or replacing

You can manually release the catch by removing the drivers side rear side trim cover in the boot area and moving the mechanism by hand
