Bug Building error after upgrade

    I'm working on an openXR project with 2022.1.23f1 in Ubuntu 22.10 and it's working fine and I can build binaries with it for Android (to run on Quest).
    Just opened the same project with 2022.2.1f1 and the build fails with several errors similar to:

    Building Library/Bee/artifacts/Android/87lik/rjkl_erences_hq.o failed with output:
    clang: error: no input files
    UnityEngine.GUIUtility:processEvent (int,intptr,bool&) (at /home/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:189)

    I've also tried with the latest beta (2022.2.0b16) and it also fails building the project.

    Any ideas on what's going on?

    How to troubleshoot build failures:

    First, make a blank project with a single blank scene and prove that it builds successfully.

    If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

    Until you can build a blank project to the target platform, don't fiddle with anything else.

    Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

    Most often things that prevent building are third-party libraries such as Firebase.

    Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

    It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

    Android build not building:

    Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

    Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:
