Pity, you're still in trouble.
I understood your problem.
There should not be anything to stuck the (original k-mount) adapter in body.

Any chance there was an Adaptall K-mount for Ricoh with the "Ricoh pin"? if so that would act like the OP describes. IF so, search for "Ricoh pin" and you can find methods for getting the mount off.

I just came to thought, perhaps the fault is not in the adapter. Could it be the body's mount lens locking release mechanism that's broken. If you've been using m42's you've perhaps not noticed it's not releasing the lock until now with the locking adapter? Just occurred in my mind

There shouldn't be anything jamming the original adapter in camera mount as far I can see looking at my adapters.
Are you using a basic manual adapter or a-adapter? A adapter has contacts. I don't know, if they could stuck with some loose screw or focusing motor screw. You could try swiching from auto to manual focusing to release the focusing screw?
Perhaps the adapter has got some damage and just bent a bit?
Here's some piece of advice copied from Photography and Imaging Resources - APOTELYT I hope it helps.
"In order to mount or unmount an Adaptall Custom fitting, it is necessary to open the lens to maximum aperture. Then, during mounting, one aligns the green dots, puts the extending tabs into corresponding slots on the aperture ring, and turns the adapter clockwise. To unlock, one presses the silver release lever, holds the lens firmly, and turns the adapter counterclockwise."

Make sure you haven't unlocked the mount from the lens. if it is unlocked, make sure it is clicked in place and be careful to remove the lens without unlocking the mount from the lens. I accidentally loosened the mount from the lens a few years ago and caused myself problems. I don't have the lens where I am now or I would be more specific.

Your English is fine.
Is the adapter rotated about 1/3 of a turn?
About ten years ago, we went on a cruise out of San Diego. I took my K10d, along with the cheap 500mm mirror lens with a T-Mount that I had just bought.
I was in the hotel room where we stayed the night before the cruise, playing around with the lens and I inadvertently inserted to adapter about 1/3 rotated. There are three locking flanges on the Pentax K-mount, so it was relatively easy to do. Unfortunately, the mount would not release from the camera.
I found a nearby camera shop that carried Pentax gear. They sympathized but could offer no help, other than to send it off to a repair facility, but I needed the camera for the cruise. They did have some tools, though. They wouldn't touch it, for fear of damaging the camera mount, but I removed the lens from the adapter and, using a screwdriver, pried the adapter out of the mount.
It turns out that the steel in the mount was stronger that that in the adapter, so the flange on the adapter bent just enough to allow me to remove it.
In other words, I used brute force. It worked and I was lucky that it did no damage to the camera.
I'm not recommending that you do the same, but it may come down to that. Its your call. I my case, the t-mount adapter could not be disassembled any further to remove it. Perhaps the Adaptall adapter can.
Good luck.
