Issue seems to be shiki failed to apply nvpatch (shikigva=12), may due to AppleGVA.framework buffer size mismatch, restore native AppleGVA.framework should work.
Restore AppleGVA.framework from usb installer, run below from terminal then reboot
sudo codesign --deep -fs - AppleGVA.framework
sudo chown -R root:wheel AppleGVA.framework.
Thank you. This helped me get VDADecoderChecker to pass.
