In V 65 the autofill function doesn't autofill anything, that's when I first realised there was a problem. No saved passwords are displayed.
The login Data file is intact, I can find all the saved passwords and the autofill works by falling back to V 64.
I am happy staying at V 64. I will wait for another software release.
I will like to have an easy and clean way to stop Opera auto-updates.
Thanks to all.
