Went to check on extensions.. lost as well, ok.. let download them back.. and bam, frozen again,
Sound like an extension is causing the issue then. Or, maybe something to do with Opera Sync after you log back in to it. Are you having it sync your settings too?
Try a fresh profile of Opera without enabling Sync and without installing extensions to see if you can still reproduce the issue. Maybe start Opera with the --disable-gpu switch just to see if it still does it.
If all else fails, create a new Windows user account and test Opera in it to see if your normal user account is messed up.
Opera isn't freezing for me or anything like that. Make sure you're fully updated though as there were recently some crash fixes.
