Thank you. I have experimented more and have found the possible cause - that I was taking on and off the lens when the camera was not turned off. I haven't tested it a lot, but it seems to work like normal (after acquiring focus in live view) when I transfer lenses when the power is off. Would this make sense? Do you think there is a faulty cable?

Honestly, I don't know if that is the cause of the issue.  I have changed lenses a lot without turning off the power and had no issues.  If that is the case, I would clean the lens contacts, and be sure they are aligned properly.  I would also check the lens contacts on the camera body side, to see if the pins are getting stuck (they are spring loaded).
