MRUK QR Tracking suddenly not working

I am making a quest3/3s app that uses QR codes for alignment, I was able to get the system working but suddenly this week I am now getting an 'MRUK Shared: queryCompleteEvent->result returned error code: -2', and QR tracking has stopped completely. The headset has stopped asking for me to confirm the environment setup before launching. I was able to confirm its broken on an old push and fresh project.

I have spent most of a day trying to troubleshoot, but my best guess is something on the headset changed, and I have done all the troubleshooting steps on the headset and unity project as possible. Any ideas here would be extremely helpful.

Ideally all i need is tracking, in fact, id love to remove the scene setup step, since the app is boundaryless and only uses the scene for QR code tracking support

MRUK/Meta XR core/Meta Interaction/SDK Essentials all V85.0.0

    I think its a bug with the new OS 2.1.
    I have a meta quest 3 with the v85 where my unity build apk works fine with qr codes.
    But the other quest 3 with v2.1 it doesnt work.

    Unfortunately it seems that updating the app packages to (v201) still didn't work.
