Hi,
I had the same problem on Kmail/Linux. I found a workaround, but haven't tested it yet on Opera Mail on Windows.
I enabled an App password and set the authentication method to "clear text" instead of PLAIN.

Opera for WindowsRE: [Solved]Operamail doesn't connect to Yahoo IMAP from last week
Hi,
Same problem with another client (Kmail) on Linux (I'm also using 12.17 regularly on Linux, and Opera Mail on Windows btw, and I'm regularly discovering new functions). Just solved it. I'll check it on Windows and Opera Mail one of these days.
- Activate 2-step verification
- Set up 3rd party app password for your client using "Other client"
- Maybe delete and re-synchronize your account using the new password
- ???
- Profit
It worked fine for me without 2-step verification until a few weeks ago. Enabling it did the trick.
However the auth method also got changed from "Plain" to "clear text" in the Kmail settings by the automatic detection, dunno if it played a role.
