The camera house seen here is as it should be. I don't have any pictures of the problem, but i have illustrated it with the arrows. The small rubber dot was stuck on the side of the camera mirror.

I used a wooden rod (a soft material) to lift the mirror with very low force while trying to take pictures (The camera will try to open the mirror)

While slowly increasing the force to help open the mirror while still trying to take pictures the mirror released.

After reattaching the lens, see step 1. The camera worked 100% fine again :)
