Cayenne_Ben or working4it, any guidance on how you solved the inability to open the hatch?

My fuse 31 is good, and when I attempt to open the hatch normally (from outside) I can see and hear the actuator arm move a bit. Through the access panel in the hatch, I can disconnect the actuator arm from the central hatch latch, and the actuator moves much further. Trying to manually move the latch mechanism only opens it part way. Not enough for the hatch to open. Something is impeding the latch.
Any guidance on if you found it was an issue with the lock mechanism on the hatch that was stopping the latch from being able to be fully released? (and if so, how'd you fix it)

I had this trouble - ended up taking it to my local specialist who opened it from the inside with some patience and tools I didnĺt have. Lock replaced (broken internally).

I used a Rockwell oscillating tool and cut the latch apart through the tiny opening between the floor and the latch. . Replaced latch and all was good

Default Hatch now opening again

I'm providing some guidance for the next person who runs into a Cayenne rear hatch they can no longer open.
It's awkward, but the interior panel can be removed from the inside. My issue turned out to be an upper latch (attached to the hatch) that was jammed / broken. With the interior panel off it was possible to force the upper latch open (there's also Jeff Spahn's approach above with the Rockwell cutter tool, but I just couldn't bear to try it...).
I also replaced the lower latch mechanism at the same time. It now closes with a much better oompf /authority sound as it pulls the hatch to a full close.
See the PDF for all hatch parts. I replaced the highlit items.

Taking that interior panel off sucks though from the inside. Feels like you'll break something but it will come out.

Do you see a clear indicator of what failure lead up to it? Like something lacking lubrication, binding or otherwise being subjected to something that leads to early failure like this?

Not sure which caused the other to fail. The latch in the tailgate was definitely jammed. I drove for several weeks on rough mountain roads without being able to open the tailgate or fully close it. It's been good since replacing both the latch in the hatch, as well as the lower closure motor.
