Hello, I just recieved my Canon EOS R and was able to use it for a few days. I am new to this type of camera and must have changed a setting I should not have. No matter what mode I am in, the camera does not seem to focus or take photos. Even the physical MF/AF switch does not allow me to focus. Any help would be great! I even tried re-setting all camera setting to default. thanks!
I was able to figure it out. The aperature setting said "F00" and I did a google search and turns out that is means it had a communication failure to the lens... I was able to re-seat the lens and everything seems to be working now.
