Received COPR and visa stamped but airline authorities said visa revoked can't fly

[Panjab95]

So i have received my COPR and visa stamped passport under SINP program. Visa issued on 26/11/2024 and planed to travel on 17/12/2024. But when i arrived at airport tried to checked in with air canada by united airlines for boarding pass they said visa is non identified and they made few calls and said sorry you can't travel because your visa got Revoked, please contact with immigration. So I reached out to my attorney and IRCC via call they said nothing is showing in their system everything looks good and I didn't even received any email or letter from IRCC. Then again next day i directly called to IRCC and they said my file is UNDER FURTHER VERIFICATION someone will contact you. Then same day i called on check file status and computer said BACKGROUND CHECK is under process. So i have no idea what's going on. I raised query through WebForm on 18/12/2024 still waiting for response or update. Does anybody else have faced similar situation or can any one advise me what to do next?? Sold everything here and got revoked literally messed me up.
