I had difficulty extruding filament and decided to open the hotend. I then found that it was clogged with plastic (as seen in the picture). The cage that holds the hotend in has fused together. What should I be doing here?

Set the hotend only to 240*, wait about 25 min & then using tweezers, try to remove the filament around the latch.

Update: I did what @lion7718 said and found that the pla matte had stuck to the heating assembly too well and it was nearly impossible to get off. After some back and forth with bambulabs, I got a heating assembly replacement.

I am having the same problem with filament melting all over the hot head. It has happened twice. The first time I just replaced the heating head. It has only been a few days and it did slit again. Help. Anyone. Why is it doing this?

I am also having the same problem after one month of owning. Clean regulary, delicate with parts, common sense and mechanically knowledgale. Warm room, allow it to calibrate before every print. Have filament dryer, tester, climate controlled room. Have not changed any of my procedures. Changed to new hot head and did the exact same thing. Hopefully something over looking, someone has found a solution, or Bambu is working on a fix.
I ran into this issue with the print not adhereing to the bed properly, then getting built up and drug around the plate and staying glued to the nozzle. From there it continues to try and extrude filament but the cooled plastic is blocking the nozzle exit so the filament just goes wherever it can to escape. What kind of build plate are you using?
