Unity no longer able to build project-CodePudding

I've been banging my head against the wall the last 6 days or so trying to get Unity to build my Android game.

My game used to build as it should a few months back, I had a couple new things I came up with and added those (the game runs fine within Unity, there are no errors in play mode).

Trying to build my game with the C compiler set to the 'master', however, consistently fails, with the following exceptions:

Building Library\Bee\artifacts\Android\fy9m9\libil2cpp.so failed with output:

Things I've tried so far:

Building with the C Compiler Configuration set to 'release' also compiles
I can build the project if I switch the platform to Windows
It seems the project can build if I set the compiler to 'debug' instead of 'master', this does not solve the problem, but might be a clue to the actual problem(?)
Making sure it was not caused by something I added: I loaded up the backup of my game (version 1.0, which worked fine and is also published), but the backup can also no longer be build.
Making sure the problem is not with Unity itself, I tried to do a build of a clean project. This works as expected.
I updated all packages in my project
I updated the Unity version my project uses to 2021.3.14f1 (which I also use for another Android project, which can be build with that version).
Updated the Google Play Games for Unity Plugin (https://github.com/playgameservices/play-games-plugin-for-unity) and accompanying code changes that were required
Per response on Reddit, I made sure that no script uses the UnityEditor namespace (the few that do, are put with #IF UNITY_EDITOR commands

CodePudding user response：

Thanks to user jdweng I managed to find the problem by looking at it from a different angle. Which led me to a post on the Unity Forums with someone who has the exact same problem I described: https://forum.unity.com/threads/fails-to-compile-on-android-arm-32.1135633/

One user there mentions a solution (credits to pradotech), which ended up fixing the problem for me:

I could build for Android using Master compiler after changing Stripping Level to Medium (I was using Low) and switching from .NET Framework to .NET Standard 2.1. Details below:

Unity 2021.3.9f1

Faster runtime

Compression: LZ4HC API

Compatibility: .NET Standard 2.1

Compiler Configuration: Master

All architectures (ARMv7, ARM64, x86 and x86-64)

Managed Stripping Level: Medium/High

I also removed some unused scripts from project.

Build completed without any errors.

Hope it keeps working and maybe that helps someone.

My project is using Unity 2021.3.14f1, I was already on .Net Standard 2.1. I changed stripping to Medium, removed a bunch of deprecated scripts and now it works again.
