Bug Execution failed for task ':unityLibrary:BuildIl2CppTask'.

I'm Running Unity as a Library inside a Native Android app, Unity Version 2021.3.11f1, I'm getting a compile error in the gradle file but not sure what the root cause is, tried all possible solutions I could try for this error but none of them worked.

Code (CSharp):

1. Build file 'xxxx\unityLibrary\build.gradle' line: 73
2.  
3. Execution failed for task ':unityLibrary:BuildIl2CppTask'.
4. > Process 'command 'xxxx/unityLibrary/src/main/Il2CppOutputProject/IL2CPP/build/deploy/il2cpp.exe'' finished with non-zero exit value 4
5.  
6. * Try:
7. > Run with --info or --debug option to get more log output.
8. > Run with --scan to get full insights.
9.  
10. * Exception is:
11. org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':unityLibrary:BuildIl2CppTask'.
