This is a harmless warning, informing you that is trying to fetch the Brave package for the i386 architecture while your computer isn't of said architecture. It's perfectly safe to ignore but also easy to fix:
This kind of error can happen when the server is too busy and preemptively starts rejecting some connections to avoid getting overwhelmed. It's also possible that it's rejecting too many requests from the same IP address, if you are using a VPN or something similar.
Another cause of this error is poor network conditions that cause it to drop packages in the certificate verification process (since it's using HTTPS). This is not within your control and can happen even if you have a good connection.
Although now that I'm checking on my system, I don't have that same repository:
https://ppa.launchpadcontent.net/zorinos/packages/ubuntu/dists/jammy/InRelease
^^^^^^^^
Is this a new installation? What version of Zorin OS are you running?
