same issue here. It was the "Aria" extension.
You need to start the Opera with the parameter "--show-component-extension-options".
After that, you will see more extensions from Opera and be able to update the outdated extension.

@sektorl you are lucky. i've tried everything (uninstall, delete opera folders, reset my opera account) and i continue with this issue

I'm having this same issue, since sunday. I have the opera 89.0.4447.12 Maybe something related with the sync.
