On an ender 3 pro. Recently the printer has started bulging where the filament will enter the extruder, but not go any farther. When i try and pull it out to check on it, it comes out only with an intense amount of force and effort. So much so ive had to remove the entire filament tube to get it out. Pictured is the broken off tip i pulled out of the extruder. Notice how much thicker it is at the right end compared to the rest.
