This is not your only problem.The only problem is my RO.
This is potentially a real problem. If you did not declare your wife, eg as unaccompanying, they could determine she was undeclared and then you would never be able to sponsor her.My wife wasn't on the application at all, just mentioned as my daughter's mother. By that time, we weren't get married yet. My wife left Canada on 2016 with my first daughter, I stayed to work and got PR in 2019. We were still together, but lived apart.
(You say 'mentioned' but don't know what that means)
If you're not clear on this, would suggest you consult a proper lawyer before applying.
The RO matter is distinct and different and opinons differ on how risky it is to sponsor before you are in compliance with the RO. (For the record, it's not forbidden, but if they evaluate your RO and determine you're inadmissible, that would make you ineligible to sponsor).
