I'm going to lock this thread as the issue with Cloudflare for Opera Air was fixed.

@SRKTheBestOfAll Thank you for your report!
Could you please respond for these questions:
Are you downloading an installer from https://www.opera.com? Do you use any VPN or antivirus software? Are you able to take a screenshot or video of this problem?
Thank you for helping to improve Opera!
Have a nice day,
Opera Air QA Team.
