Which version of ARCore Extensions for AR Foundation 1.45 are you using?

Before 1.45 the prototype AR Foundation 5 suport we used defines like ARCORE_USE_ARF_5 however now there are 2 versions. See the release of the Unity package tgz on github here:

https://github.com/google-ar/arcore-unity-extensions/releases/tag/1.45.0

You can see there are 2 packages now:

• arcore-unity-extensions-1.45.0-arf4.tgz
• arcore-unity-extensions-1.45.0-arf5.tgz

Given your problems I think you are using the AR Foundation 4 (ARF 4) version but you want to use the AR Foundation 5 (ARF 5) one. Tell me if I have this wrong.

The new ARCore Extensions for ARF5 package should make it easy to run ARCore samples out of the box with out defines like ARCORE_USE_ARF_5. This fixed the bugs in our samples where XR Origin on our ARF 5 scenes was null.

I think you're right, I started from scratch and using the following link : https://github.com/google-ar/arcore-unity-extensions.git#arf5

Per the instructions here - https://developers.google.com/ar/develop/unity-arf/getting-started-extensions?ar_foundations_version=5

Has worked with a windows unity build 2022.3.43

It's still an issue when changing / upgrading an existing project for some reason. Resolution is to start from scratch and move the rest of the application over to the from scratch build. AR Foundation has been 5.1.5 throughout the process.
