What are these rings in the photos from EOS R ?

I got my EOS R yesterday and on my first test run, I got dark rings on the photos. Rings are not consistent. Some photos come without these rings. And the shape of the rings is not consistent as well.
Could you please help me out to figure out, is this something fixable on settings or is there any issue with the camera?

Sample photos are attached.

I shot them all with a Sigma Art 35mm F1.4 and a Canon Control Ring Mount Adapter EF-EOS R.

I used this Sigma lens before on my 5DM3 and never encounter such an issue.

Shot 01 - Few rings visible

Shot 02 - Two rings visible

Shot 03

Image 04 - No Bands/Rings
