Do you have any Railclone in the scene? I had something similar recently. i.e. same corona error message and the viewports were behaving crazy as if an object was miles away from the origin. Worked out it was a simple railclone object causing it (when turned off the problem disappeared) . I couldn't fix it so just deleted and rebuilt the railclone and that fixed it.
Edit - Ha! forget that, was scrolling through unread posts and didn't realise this was a C4D post, so cant be railclone for you.
