Err 01 and black spots on Review screen 6D

[PhotosByNeva]

I recently went to Monument Valley on a workshop. Right before I left I started getting the err 01 msg about the lens connection with camera.
Now after I take a picture, my viewing screen will go back and forth making the sky, sun, any bright part black. I have not downloaded the pics yet to see but I believe it is only in the camera. I have 3 lenses the error was only happening with the 28-135mm, now all 3. HELP?! I would love to add a picture of my screen but don't think I can on the mobile app.

Contact Canon Support.  They can best guide you to getting your camera repaired, if it is possible.

Yes I found out and figured out how to turn it off, it was really bothering me. I've had my 6D less than a year and before that I had a rebel so there's a bunch of new things I'm learning.
