RE: clogged filament
1. try to do a cold pull (see https://help.prusa3d.com/article/cold-pull-mk4-xl_445071 )
If it is not possible to load/unload filament, try to heat the nozzle to maximum temperature so that the filament gets fluid. Maybe it will flow out of the nozzle.
If not, try to use the acupuncture needle to open the nozzle.
I had similar issues with the clogged nozzle, but mine already printed about 35 rolls of filament.
I ordered a new nozzle, but right now it is working after declogging.
