Question Building to Android stalling at initial scene

I'm encountering this error when attempting to build the app bundle for my Android game.

Code (CSharp):

1. Win32Exception: ApplicationName='D:\BookshelfBlitz\Temp\PlayServicesResolverGradle\gradlew.bat', CommandLine='--no-daemon -b "D:\BookshelfBlitz\Temp\PlayServicesResolverGradle\PlayServicesResolver.scripts.download_artifacts.gradle" "-PANDROID_HOME=D:/2021.3.18f1/Editor/Data/PlaybackEngines/AndroidPlayer\SDK" "-PTARGET_DIR=D:\BookshelfBlitz\Assets\Plugins\Android" "-PMAVEN_REPOS=https://unity3ddist.jfrog.io/artifactory/unity-mediation-mvn-prod-local/;https://android-sdk.is.com/;https://maven.google.com/" "-PPACKAGES_TO_COPY=com.unity3d.mediation:mediation-sdk:[1.0,2.0[;com.unity3d.mediation:unityads-adapter:[1.0,2.0[;com.ironsource.sdk:mediationsdk:7.2.7;com.google.android.gms:play-services-ads-identifier:18.0.1;com.google.android.gms:play-services-basement:18.1.0;com.google.android.gms:play-services-ads:21.4.0;com.ironsource.adapters:admobadapter:4.3.34;com.ironsource.adapters:unityadsadapter:4.3.25;com.unity3d.ads:unity-ads:4.6.1" "-PUSE_JETIFIER=1" "-PDATA_BINDING_VERSION=4.0.1"', CurrentDirectory='D:\BookshelfBlitz\Temp\PlayServicesResolverGradle', Native error= The system cannot find the file specified.

I have previously attempted to use google play games plugin to authenticate my players, but decided to remove it , so not sure if this is the cause of the error, or i have accidently deleted a file that i thought was to do with google play games but was actually related to ad mediation. I'm kind of lost as I'm not even sure which file the system is looking for.
