I was able to get the camera displays turned back on and most functions work, BUT.......I cannot switch out of C1 or C2. As soon as I switch to any other mode, the camera goes dark, and nothing works except the flashing err 70 in the little display on the top right of the camera.
I have reformatted the card to no avail. If I switch to any other mode, I have tp remove and reinstall the battery before I can get the camera back on in C1 or C2.
Is there a solution to all of this. All I did was download a very popular astrophotography image capture program and plug the camera into my laptop. Apparently the 6D Mkii didn't like that for some reason. I have used that program for years with other Canon cameras with no problem.
Also, if I try to go back to factory settings............the camera will not do that in C1 or C2 modes. Catch 22!!

Did you ever get the issue resolved? If so, how? I can only use my 6D Mkii in C1 or C2 mode. In any other mode the camera goes dark and nothing works..........except the blinking err 70 on the little display on the top right of the camera.

Easy. I sent the camera to Canon for repair. They repaired it under warranty and it has worked flawlessly ever since. That was more than 14 months ago, I believe.

Remove battery, lens and memory card. Close battery and memory card doors.
Turn power switch to ON position, press shutter button and hold for 30 seconds to 1 minute. Turn power switch OFF.
This should clear internal memory and reset to factory conditions.
Refit battery, close door, turn power switch ON.
Thanks for taking time to reply. Sounded good—something I had not tried. Alas, it didn't help. Appreciate it anyway.
From what's been said so far, this sounds like the sort of problem that might call for a firmware update. Have you made sure that you're using the latest firmware version? (I'm assuming that a firmware update can be done in C1 or C2 mode, though it's something I've never tried.)
