Scouser a couple things that stick out:
Failed to connect to the EdgeTPU service
An error about this shows up many times, so this may be the actual cause? Not sure, but maybe you will want to enable Settings > Apps > Special app access > Special access to hardware accelerators for Google apps
from the owner profile.
No ARCore package found.
Maybe try installing that app from Google Play
And, lastly, if you didn't grant the Pixel Camera app access to the internet/network right after installing it, you can try enabling the network permission for a while. Enable that, launch the app, play around with it, then disable the network permission. The Pixel Camera app, if I recall correctly, downloads some stuff from the internet to do some of its fancy AI stuff.
