When a selenium worker is attached to a pay-for-solution captcha service the infinite loop of captchas that can be solved but don't provide access would be meant to drain you financially. You uncovered a pretty sweet (dark) pattern implemented by Cloudflare to screw bot owners.
This is just #2 and #3 combined.
It sounds like this is working as intended and also wastes your time with un-passable captchas instead of you spending more time trying to figure out how to get around their bot protection.
Another observation here is that you really shouldn't be hacking some scripts on top of your bank login. The banks know this and they are trying everything possible to dissuade you from doing this.
