I used the following website: https://browser-compat.turnstile.workers.dev to troubleshoot. Following the directions, here's the info it wanted me to share. I tried the official website, but there was no obvious way to connect with someone about my issue, or even open a ticket, and when i tried the community post I kept getting errors.
Here's my problem: Cloudflare Turnstile is not working on Opera GX even with VPN turned off, date and time correctly synchronized, and no other extensions enabled. IT works fine in Chrome. It works fine in GX Incognito. But normal browser just doesn't work.
Below is the information I was advised to copy and paste:
