*Steps to reproduce:*

1. Create a blank project in Unity 2021.3 for Android

2. Make sure the “Target API Level” is set to API 34

3. Enable custom Gradle Template for 'unityLibrary'

4. Under 'deps' add " implementation "androidx.legacy:legacy-support-v4:1.0.0'""

5. Enable custom properties and add Jetifier & androidX
6. Build project.

Or get the zip folder attached (from Scopely's test project)

*Actual results:* 
Build fails with
{code:java}
Execution failed for task ':launcher:processDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction
> AAPT2 aapt2-4.2.2-7147631-osx Daemon #0: Unexpected error during link, attempting to stop daemon.
This should not happen under normal circumstances, please file an issue if it does.{code}
This library, alongside with v13 is one of the core Androidx legacy libraries and used by SDKs such as Facebook, OneSignal etc. Usages [examples . |https://mvnrepository.com/artifact/androidx.legacy/legacy-support-v4/1.0.0/usages]

It is currently not know if other Libraries are also affected - I have tried sporadic androidX libraries but they compiled OK.

*+By August 31st 2024, users are required to target API 34 in order to update apps on the play store.+*

*Expected results:* 

Build compiles with no errors

*Reproducible with versions:* 
2021.3.x with targetSDK 34 and AGP 4.2.2 / Gradle 6.7.1 / Java 8 / Buld Tools 30
2021.3.x with target SDK 34 and updated build-tools to 31/32/33/34

Test result from others
AGP 4.2.2 / gradle 6.7.1 / 33 - success
AGP 4.2.2 / gradle 6.7.1 / 34 - fail
AGP 4.2.2 / gradle 7.6.2 / 34 - fail
AGP 7.0.0 / gradle 7.0.2 / 34 - fail
AGP 7.0.0 / gradle 7.6.2 / 34 - fail
AGP 7.1.0 / gradle 7.2 / 34 - success
AGP 7.1.0 / gradle 7.6.2 / 34 - success

*Not reproducible with versions / combinations:* 
* Unity 2022, Unity 6 and default java/agp/gradle setup
* Unity 2021 by exporting the 2021.3 project and changing the Gradle version to 7.2 and the plugin to 7.1.3 externally 
* Unity 2021 default java/agp/gradle, target SDK 34 AND changing compileSDK to 33 through a custom Template

*Notes:*
* This is not a Unity issue because the same behaviour is exhibited with a blank Android project with AGP 4.2.2 and Gradle 6.x configuration that targets SDK 34 and imports these libraries. ([link|https://discuss.gradle.org/t/build-failed-on-agp-4-2-2-with-gradle-6-7-1-when-compilesdkversion-34/46541])
* It seems to be an issue with gradle/agp itself
* compileSDK to 33 is a dirty temp solution because it may conflict with other plugins' requirements
