Hi Vitaliy,
Thanks for asking. Unfortunately, this is correct - VrApi library support was deprecated on 31 August 2022, and our documentation was updated to reflect this change. You may be able to use VrApi if a waiver is provided, but it's likely that you'll continue to experience incompatibilities with newer OS versions as VrApi is no longer a supported library and we're only fixing critical security, privacy, or safety bugs.
I wish I had a more convenient answer to give you, I understand how time-consuming that migration is likely to be. You can check out the official post from July 2021 for more information and suggestions on migrating to OpenXR if that's helpful.
