@sgunhouse I'm running W10 v1709 (build 16299.46.1).

@leocg tried moving the profile folder, no luck as I'm still getting the same error.

Opera internal pages are not working (Settings, about, extentions, etc.).

@leocg thanks for the link. The issue is that even opera pages (opera:about, settings, etc.) are not working.
I'll try creating a new profile.

Hi everyone

I'm a long time Opera user but I've never seen this error before. Last week one of my Opera instances died out of the blue. I tried reinstalling, removing and installing from scratch but this is still happening.

Here is a screenshot of the issue. All my open tabs are showing the same message, clicking the button fixes nothing, closing the browser, reinstalling not working either.
