I'm getting a notice when trying to enable synchronization on Opera GX and I'm encountering this issue, https://i.imgur.com/QhBu810.png, I've tried different accounts, turning it off and on again, signing out and back in, and nothing works. It's just for my current PC but works fine on my laptop as far as I know.

For me, on all but my current computer, Opera and OperaGX both show this, https://i.imgur.com/QhBu810.png. I have tried to start another account as well as signing out and back in several times, even changed my MAC addresses for my wifi, ethernet, and bluetooth just to ensure it's not an error there.
