Steps to reproduce:
1. Open the attached user's project "XRAndroidBug.zip"
2. Export an Android project build
3. Check whether "Build/unityLibrary/src/main" contains "AndroidManifest.xml"
4. If you try and build the project with Android Studio it will fail as the manifest is missing

Expected results: Importing XR Management 4.3.1 or newer does not result in the exported Android builds failing and AndroidManifest.xml is not deleted in OnPostprocessBuild
Actual Results: Importing XR Management 4.3.1 or newer results in exported Android builds failing, because it deletes AndroidManifest.xml in OnPostprocessBuild

Reproducible in: XR Management 4.3.1, 4.3.3 (2020.3.48f1, 2021.3.25f1, 2022.2.18f1, 2023.1.0b16, 2023.2.0a14)
Not reproducible: XR Management 4.2.1 (2020.3.48f1, 2021.3.22f1, 2022.2.15f1, 2023.1.0b12, 2023.2.0a3)

Notes:
-A workaround is to embbed the package and delete the code that causes the issue in XRGeneralBuildprocessor:
public void OnPostprocessBuild(BuildReport report)
{
// Always remember to cleanup preloaded assets after build to make sure we don't
// dirty later builds with assets that may not be needed or are out of date.
CleanOldSettings();

// This is done to clean up XR-provider-specific manifest entries from Android builds when
// the incremental build system fails to rebuild the manifest, as there is currently
// (2023-09-27) no way to mark the manifest as "dirty."
CleanupAndroidManifest();
}
