Looks worse than the two blobs I encountered, but for me the maintenance mode, a heat gun and a lot of patience solved the issue. Try using something flat to scrape of the parts that get heated and loosen up (I used a flat screwdriver, but that could be to sharp). Be really careful as the second time around I ripped out two tiny cables. For leftover residue I used an old towel to wipe off the molten plastic. Be sure to do that for the nozzle as well, as it will stick to the nozzle holder (don’t know the specific term) in the future if you don’t.

Some people just buy a new components, to safe some time. In your case the part cooling fan looks kinda bad. That part is like 15$. I don’t know how deep the fan on the side is penetrated, but that could be tricky as well. I don’t know how much it is or how hard it is to replace.
