I would check the front cooling fan is spinning and working right if the filament had grown a ring around it outside of the print core, as you might have had heat creep due to front fan not working/spinning free.

I had more time to dig in to it. I loosened the 4 long screws to drop the head down to see what was going on.
the filament is in fact stuck in the head end of the boden tube.
the filament had developed a ring around it just outside the top end of the print head tube. Probably due to a clogged nozzle. as the filament was softened and te extruder pushed agains the clogged nozzle it created a ring.
that ring is just a bit to big to pull through the bowden tube.. when I originally tried to extract, I pulled as the extruder was reversing... that logged the filament in the bowden tube.. That's also why I could not pull the bowden tube out the printhead end.. it was expanded by the ring on the stuck filament.
Its real stuck in there with nothing showing at the printhead end to grab to pull it out... so I'll probably just get a new bowden tube.
Also I'll put the printhead back together and get the nozzle off to see if it needs cleaning.. or a new nozzle
