There seems to be a bright overexposure running along one edge of my photos, seems to be the bottom of the censor maybe. Anyone else experience this? I am using a Canon EF adaptor and a Sigma 35mm lens.

You really need to post a picture so that we can see this. If it is appearing at the bottom of the picture then it is at the top of the sensor.
Does it happen with a standard Canon lens, some adaptors can suffer from internal reflections that cause bright spots.

Which edge is overexposed?

Are you using any strobes or flash? Were you using the silent shutter? If the answers are "no and no", then you need to contact Canon Support.

Yes, I was using off camera flash, but no to the silent shutter. 1st Curtain electronic.
Edit: Confirmed, this happens when using Electronic or 1st Curtain electronic. Not mechanical shutter. I also noticed it happens when the shutter speed is above 1/250th of a second. At 1/200th I do not see it.

So can anyone tell me if this is a problem with the sensor or is it because of a Sigma Lens and Canon EF Adapter? I never had this problem with my Canon 90D. Thanks in advance.

I have seen this before with the EOS R. Why it happened I never figured out, but randomly some images would have an oddly bright edge similar to this, always on the right/bottom edge. Haven't noticed it on the R5. It could be lens related, you never know. I would try a Canon lens if you have one.

I think if you stop using the silent shutter with the flash/strobe, then the issue just may go away.
