When I take a single photo with my R8 camera using the Cannon EF mount adapter and my Rokinon14mm F2.8 Full Frame Ultra Wide Angle (w/ built in chip), My R8 will freeze up on me. The screen goes black, the shutter fires like it is taking a picture, the red buffer light turns on, and it gets stuck like this indefinitely. Not only do I have to turn off the camera, I need to remove the battery.
The 14mm Rokinon lens works with my EOS Rebel T7.My Cannon EF to RF adaptor works with my Sigma 70/200mm lens. I turned on "Release shutter without lens." I have not seen any more suggestions on any forums.

Gravity,
Yes, the aperture is a function of the lens, not of the camera. If your aperture is showing a blank screen, it means that the camera is not electronically communicating with the lens.
You wrote, "Taking a single picture should be fine and it works specifically with every other lens."
Time for a different lens, methinks.
