Remove the Bowden tube from the top of the Nextruder push some filament through on the right side, push out the broken pieces.

That happened to me too. Unfortunately, I caused the problem myself. I usually always use PTFE tubing with a 3mm inner diameter. But when I replaced the tubing, I ended up with one that was 2mm.The filament got so tangled and jammed up that I had to throw out the entire PTFE tubing along with the filament :-DSo: Please also check if you have a PTFE tube with a larger inner diameter. Just my opinion.
