I had the same issue during last weeks. I tried a lot and played around, because as a Merchant Integration Manager I want to understand how to fix stuff and make it work again instead of completely delete and reinstalling something, because reinstallation is not an option in the most running customer production environments.
So first of all, here is how you can do the whole stuff that @davidoliver-1 mentioned in his post:
- Right-Click to your OperaGX in Taskbar or Start menu and select "New Private Window" instead of starting it normally
- Now OperaGX should start and you are able to access all required functionality to do the magics that @davidoliver-1 described.
- In my (first) case where I faced this issue, it was enough to just start OperaGX in private mode one time. After I closed it I was directly able to start it in normal mode again and even if all of my previously opened tabs where gone the browser did his great work as usual.
Additional information from the 2nd time I've faced this issue:
- Today - about two weeks after the story above - starting in private mode wasn't enough. The browser closes and closes himself again and again. No chance to make any changes and even the cli start with
--disable-extensions
didn't work. - At the end of the day I opened it in private mode and then I switched to the settings and extension settings. In extension settings I got information about a broken extension, and I removed it completely.
- Additionally, I removed cache, browser history, stored tabs and so on, just to make sure that this was not another reason for the behaviour.
- Afterwards I left private mode and restarted in normal mode, and everything works absolutely fast and smooth again.
I really hope it may help you guys and even if I'm not an Opera employee I really appreciate this browser!
