I have dealt with dozens of stuck posts. Mostly successfully. What is the frame material, and the post material? The solution is predicated upon that answer.

Summoning @jklett …
put post in vice, twist frame for leverage.
something will give. i'll bet on the top tube at the seat tube - but maybe the post will come out.
assuming you pour the pb in from the bottom??
don't ruin it for me.

It's the dropper post being stuck in the up position, not the post stuck in the frame. The solution needs to fit the problem, not the other way around...
ah, i think my idea still works, cause gotta throw the reverb out.
i have a transfer for sale.

I usually try some intermediate measures before the post-in-the-vice route (which will need three un-distanced people to hold the workbench).
A BMX 2-piece stem attached to the post as though the post were a handlebar, and a fork steerer tightened in that stem, will give a lot of leverage in the right spot. I have done well using a heat gun on (depending on materials) the post or frame, to get the penetrating oil everywhere.
Soak. Time is now on your side.

This is the part of the problem I am addressing.
Nah, post is stuck in the frame. Pretty sure the unit itself is trashed but I can’t even assess the situation until I get this fucker loose.
Aluminum. I’m way too rough on bikes to own carbon.

I should have been reading the whole initial post. Foot in mouth once again. Sorry @Patrick @Fire Lord Jim...
I will play the jolly and call on...
Might be interested if I can’t rebuild this one.I have an internal Reverb for sale.
It works. 31.6 I think. Will likely need to bleed the line because internal and you always lose a few drops feeding through the frame. No refunds because SRAM.
$50. I'll lower it to you in a bucket from apartment window in Mahwah.I still think that most Reverb issues are because people typically set them up in the summer and pressure drops in the winter. I set mine up for the first time when it was cold as shit and never gave me issues. Just removed because rigid FTW.
I don’t think temps have anything to do with it since it survived 3 winters and lots of snow rides. The fact that it’s stuck in the up position has me hoping it’s just the remote line. What length is yours? My frame is a small so I don’t think I can fit 150mmIt works. 31.6 I think.

For aluminum post in aluminum frame, I would use the heat gun on the frame to spread the penetrating oil. Don't melt the paint, but it should get too hot to hold.
I would do that a few times, letting it cool between, each time adding more oil from above and below.
For the final heat, I would already have the BMX stem on the post, ready for torque. Once the frame is heated, quickly cool the post--maybe shoot it with a CO2 cartridge. Then hammer on the steel fork you put in the BMX stem for leverage.
Sometimes it breaks free, other times it breaks the frame at the collar.
If you get a little movement, go back to oil & heat. You will likely save the frame.
Good luck. If you ruin the frame, all that oil will help it burn.

Do you have a vice? Put the post in the vice (bike upside down). Use the frame as lever and twist.
73% sure it's 125mm. And the cable is long. Can measure over weekend unless you need it asap.
If you used the dropper more than 3 times a year you would eventually have had problems as well
Sweet. If bleeding the remote line doesn’t fix it I’ll take you up on that. First I gotta get the damn thing out of the frame.
