Cannot build the app due to errors

[alanspace]

Hello @dilmerv,

Thanks a lot for your great demo! However, as a newbie to this fascinating technology, I encounter problem in building the app due to the following errors, no matter what versions of unity I have tried (2023.2.3f1, 2022.3.13f1, 2021.3.32f1, 2020.3.34f1, 2019.2.2f1) in mac intel.
I want to try Measurement scene, but I cannot even enter the play mode since the console required me to fix the errors first. Here are the errors I have got from 2023.2.3f1.

All compiler errors have to be fixed before you can enter playmode!
UnityEditor.SceneView:ShowCompileErrorNotification () (at /Users/bokken/build/output/unity/unity/Editor/Mono/SceneView/SceneView.cs:3919)

Pleas kindly suggest if there is anything I need to import to the project, thanks a lot for your effort!
