Olympus XA2 One diaphgram blade dropped, while images extremelly dark

Hello there, I have pristine cosmetics Olympus XA2 , it was taking extremelly dark images and at last try , there was no image at the film. Then I found single diaphgram piece slide from viewfinder camera gap to out.

Is this piece caused dark images or no images. While looking out from lens , there is asymetric blade workout.

Now can I take pictures ?

No, and I don't think it would be an easy camera to repair.

The repair manual is available:
