M90 cassette player stuck when in place

[Dancorp]

I would like to ask for your help once again.

The cassette player works well when it is extracted from the boombox, but once put back in place, it seems to appear a kind of blocking that activates the autostop.
The only thing that changes in my eyes, is the positioning of the cassette since it is in the door when the player is in place.

Any idea?

Is the counter belt getting caught on something in the case?
Auto-stop engages if the magnet wheel on the tape counter isn't turning while the deck's running.

A priori no link with the belt of the counter. Because when I block it voluntarily the tape is eaten
Here is a video of what happens if I simulate the presence of a cassette tape

Problem identified.
It was a bad positioning of the ejection lever. This one slightly activated the mechanism indicated on the picture.
