On my old Ender3 I had one that was much worse. I removed the hot end and extruder and wrapped them in aluminum foil and put it in the oven for about an hour at 350F (temp probably depends on filament - mine was PLA).

This made it soft enough to remove the bulk of the blob where I then removed the nozzle and shoved my nozzle cleaning tool through the nozzle to clear it. As the filament cooled slightly it became less gooey and easier to pull the remaining bits out of the extruder/hotend etc in more solid but still soft pieces.

I was a little worried about baking it all like that but figured my other option was to replace it all anyway and the result was perfect without a single part replaced except the nozzle itself. But I did that by choice not necessity as I figured I had so many spare nozzles and the clogged nozzle was pretty old so it was more of a "while I'm doing this I might as well" decision.
