An error occurred. (Error code: 9) (Extra code: 0)

Thanks for reporting this, xavieredouard! Is your Canary still updating itself even though it's showing this error on settings? You should see the v99.0.1140.0 build today, for instance. 

We recently released some fixes for this, but since you're seeing it on a very recent Canary build it looks like you might be hitting this error for another reason. Do you mind submitting feedback in browser (top right ... menu > Help and feedback > Send feedback), checking to include diagnostic data, and letting me know what you put in the description so I can grab it for the team to review?

Thanks!
