I’ve already replaced everything, everything is new, back and middle cover and this piece on foto is also new that is stuck now….

Even at Support I get the same article about Cutter Assembly. I have never removed those cutters.It is stuck at the top where the magnet is.

I found the cause. You need to install the Middle Housing first and then the back cover. Now it doesn’t get stuck anymore…
