Goodnight:
The same thing happened to me and, after a while of anger, I went back to version 58 because I do not have access to my extensions. I'll hold for a few days waiting for it to be fixed soon. If this does not happen, I would leave Opera again (as I did many years ago and it took many to return to it). It would be a great pity but the truth is that I am already updating other browsers. Just in case.
Goodnight everyone.
