How to recover from Canada's refusal to sign a super visa twice?

Of course you can apply. It doesn't matter if you refuse the visa many times. As long as the binding force of the next application is higher than before, it is entirely possible to pass. It is unfounded to say on the internet that refusing a visa twice will definitely fail. Whether you can sign it next time depends on whether you can improve your binding force and prove to the embassy that your purpose is real and you can sign it. It is suggested to use high-end customized group processing scheme, which can quickly improve the binding force in a short time. You don't have to join a group, you can go by yourself, just like your own, but this kind of handling plan needs the strength of large state-owned institutions. You can consult the online website, which is a national research institution specializing in visa refusal and re-signing. Many Canadian applicants who refused visas many times passed through them. I hope it helps you. I wish you a successful visa in Canada next time.
