This is a standard procedure. Biometric is first thing that happens after you apply - it initiates background checks in Canada. Next step will be for the officer to evaluate your HC arguments and decide on AIP. By the way, this is a big gap between application date and biometric - almost one year. Usually biometric request is issued same day or next after AOR, whereby AOR comes 1-3 months after applying. So it seems that due to delay in your AOR they held off with biometric too. This was supposed to happen in March-June 2022.
