filiment stuck in hotend

[skylab]

i recently purchased a used voltron and it worked for 5 minutes some filament broke off in the hotend and, i tried the usual tricks of heating it up to 280 trying to put the obstruction out using a wire, but nothing seems to be able to disloge the blockage and ii dont want to break it y forcing it too hard and bending the frame or breaking something else.. my last resort before disasembing it is to reach out here for any ideas

What is the hotend, extruder, and toolhead type?
What caused the blockage?
