You don't need 2 filters on @ the same time, only the CPL. Now you'll need much patience in trying 2 remove the 1 that's stuck?

No. That is NOT what “appears to be”. Read the opening post.
You are inventing stuff. Nearly all PLs have a knurled grip area for attaching and removing the unit by its own base support ring. The rotating front unit is not involved at all.
The OP has encountered a fairly common situation that happens with some filters and it is unrelated to whether the filter is or is not a PL.
From OPs post, I mount them with the CP lens first followed by the UV for protection.
You don't need the UV, just the CPL? i use the CPL alone & get pleasing results. UV just 4 protection when storing.

Thaz for sure !!!! Huge AMEN on that.

It's certainly fortunate that we have one "genius" we can count on to provide unerring direction to any photographically related material.

You are correct in saying “as if it has no threads”. You have run it in past the threads.
When you bottom out the filter into the lens the threaded areas of both items have gone past each other. Just pull the filter forward as you unscrew it, so as to catch the threads.
The few times you had no problem, there was likely less than about 1/10 turn of threading still engaged, but in normally snugging the filter into place you wore away the fragile bit of plastic. It’s a cheap design, not abuse on your part, thaz at fault.
In sadly typical UHH manner, no one else has read what you plainly wrote. Keep that in mind next time you seek advice from these faux experts. They seldom if ever read what is right in front of them :-(

Immaterial, a red herring. Doesn’t matter at all what he does with his UV filter.
UV , just 4 protection?

If the filter mount on the lens you may have cross threaded the CPL.
The non revolving part of the CPL is what screws into the lens mount. This is what has to turn to remove it.
Using two fingers to remove it puts two pressure points on the filter, 180 degrees apart. This can and often distorts the filter ring much like an egg shape.
If your fingers can get good purchase in the mount ring, try using three fingers to remove it. The first, third and thumb spread like a claw so each finger is about 120 degrees apart will not distort the ring as much as two fingers.
Aloso you can use masking tape to tape the rotating part to the non rotating mount so they in effect become one piece, several rounds of tape would be best. That may allow you to unscrew the mount. Tape would also help with a filer wrench.
In days of when film was gold, I carried my filters screwed together between stack caps. Occasionally they would stick and I would just gently tap the edges on a hard surface, going around. the rim like trying to peel a hardboiled egg. This often works with lenses that have metal filter mounts.
Another way is when a filter is stuck on a lens is to hold the lens in one had and cover the filter with your other palm. This distributes the force around the filter more evenly.

When I bought my Nikon 18-200 lens I also bought a UV filter and a circular polarizer filter for it. The UV stays on the lens all the time for protection. I have used the CP lens several times and at no time had any problems attaching or removing either filter. I mount them with the CP lens first followed by the UV for protection. Today
I removed the UV but the CP lens would not come off. It would not unscrew, it just revolved as if there were no threads. Then I found it would not tighten up either, not in the least. Now it will neither come off nor seat. If anyone has had a similar experience and solved the problem I would appreciate hearing from you.

If you are going to use two filters in the future, then attach the CP to the UV, however, I suggest that you use only one. I suspect that when you attached the UV to the CP you may have over-tightened the CP. since you attached it to a rotating element. I would use a rubber jar opener to grip the fixed portion of the CP or rubber gloves. Twist it gently. Another poster suggested using a rubber band over the non-rotating portion of the CP and then grip only the fixed portion of the CP. if you are not sure about what you are doing or the CP does not loosen up, then bring it to a local camera shop. Be careful not to damage the threads on the lens.

There is no stuck filter involved here. Try reading the complete original post before writing a lengthy reply about something entirely else :-(
Nothing is stuck or jammed. The OP has described the situation quite clearly and accurately. Verrrry easy to understand. The entire assembly is *rotating freely* in both directions, so where is anyone possibly reading that anything is stuck ?

Just parse the description of the situation in the opening post.
Trying to unscrew a filter (snugly) mounted on a CP (not necessarily "stuck") without holding the top of the CP will afford the same results, continued rotation of the filter.

Thanks for pointing out my failings Mr. Perfct.
