if you can get it to rotate it might come out easier.
question, did you pull the horshoe shaped clip?

We have all dealt with the PosiTemp cartridge in one degree or another of frustration. Sometimes we are successful, other times we are not and have to replace. With no stem to grab, you have a challenging situation. I have used a very low flame torch (hobbyist butane type) to melt the plastic cartridge away and expose enough of the stem to where I could grab it with ViseGrip needle-nose pliers and extract it.

I've used a bi-metal hole saw and drilled out the majority of the cartridge and peeled out the remainder. What ever method you use just be careful not to damage the valve body.

When that happens, you have to "play it by ear" and try many methods to remove it until you are successful.
