Rto India — NOC related issues

I have moved from Bangalore to Gurgaon and I have taken an NOC for my bike from Bangalore RTO in favour to Gurgaon RTO . But now When I approached to Gurgaon RTO they denied me for re-registration saying Delhi NCR has banned all vehicles re-registration which are purchased out of NCR before April 2022 . So What will I do now ?
If Delhi NCR dont accept the other state moved bikes then why is the NOC issues successfully ? Please help.
