Filament blocked in the extruder chamber

Hello eveyrone.

First of all, I have an MK3S with an MMU2 I am using for a year now and I get really clean prints.

But on my last prints, the filament is blocked on the extruder chamber. When I start the print, the MMU load the correct filament, the print goes well, but my problem comes when the print is finished. The MMU will try to unload the filament and it will fail. Indeed, after checking, I get a little blob on my filament.

Here are some pictures.

I don't know if the pictures are really clear but at the end of my filament I get a small blob which won't allow the filament to be taken back by the MMU. It happens with different brands of PLA and I haven't another material to test with right now.

Does this happened to someone ? Any idea to solve this problem ?

Thanks for your replies.
