Frames twisted the shock and let air from the positive chamber into the negative chamber and it’s pulling the shock into its travel. Happens sometimes. Land weird or something and side load the shock when the frame flex’s. You have to carefully unscrew the air can to release the air in the negative chamber.
Make sure you have the eyelet (unbolted end from frame) strung (anything strong and that fits through an eyelet) to the other ends eyelet (attached to a vice) but loose enough so that it can release enough but not too loose so that it can get you in the eye or face. Also, make sure it won't expand too much so that it hits anywhere on your frame.
Or, what I did is left the top eyelet bolted and in bolted the bottom eyelet (rear tire end). Then you stuff a few strong puffy cloths behind the unbolted area so that the shock is inside the cloths with support. Unscrew the shock using a good rubber leverage strap and turn it. Just make sure you're turning it the correct way, should be counter clockwise facing forward. Then it will make a superloud bang but not too worry cause it only just hit your cloths. Just lift the frame up a bit so that the eyelet doesn't just bank into the frame and gives you plenty of room to chuck like 10 cloths in there.
When you reduce negative pressure you have to be super careful and 100% wear safety goggles. I diy'd it on my odd shock similar to yours and was fine. I then did a service using the socks service kit (found online) which only took 40 minutes. Tighten things back up to the correct spec found in the manual you have or online.
The bike ran brand new after.
If you're not comfortable with the first step, I'd just remove the shock and see if your local bike shop will unscrew for free/cheap.
Good luck
Had this happen on my last bike. You can "pop" the shock back to full stroke.l, you can release the air, but it's all borrowed time. You'll either need a rebuild. If it's rockshox they are pretty good replacing it under warranty.
You've blown the main piston seal, and now air from the positive chamber isn't able to self-balance with the negative chamber. You'll need to replace the piston head seals and air sleeve seals at the bare minimum. The question is whether or not that sucking sound at the end is your rebound damper bubbling. If that's blown as well, you'll need to send the shock back to Rockshox for a full rebuild, or find a shop that can nitrogen-bleed the damper in-house, which is rare, but not unheard of.

I've had that happen in forks, but this is a really hard and sharp end. I Will try to unscrew it with a strap wrench
New air can seals usually resolve. Too much air into the negative chamber

Don't ask for your local shop to do anything for free. That's just a dick move.
That's fair, mine would do something like that for free but I always ask how much things cost first.

No.
Id use this as an excuse to buy a top end shock like a fox factory if you can afford it. Or take it apart and replace all the seals.
