EOS R6 Purple line across photos.

I bought an R6 refurbished for myself for Christmas. Was delivered yesterday and my photo has purple line vertically going across it. I always use the eye piece to take photos. I didn’t notice it at first so I thought it was the screen. Then it showed up on the photo. I am pairing it with a 50mm prime and the canon adapter. On the LCD it seems like the line flickers a bit so it’s not every photo. But most have it. I have already started a return/service with canon. I am a CPS member. Any ideas? I attached a photo of my son for reference. Left side of photo.
