Brewing unit cannot be removed

I wanted to clean my Kaffesolo 950-103. To do this, I moved the lever of the brewing unit down (6 o'clock). Now I can neither remove the unit nor move the lever back to the "locked" position.
Who can help?

Take out the drip tray and try to press from the inside. The rubber on the pin of the drive will have swollen. Then grease it a little or replace it.

Thanks for the answer, unfortunately negative.
The unit sits bombproof:angry:

Is the brew group in the home position?
See picture. The marking on the shaft must be at 15 o'clock (arrow).
