android-manifest File not found Error, while imtegrating ChartBoost

Hi I am integrating ChartBoost SDk in Unity, where as i have implemented Applovin already. Applovin Works perfectly before ChartBoost but with chartboost it gives Error;

FileNotFoundException: /Applications/Unity/Unity.app/Contents/PlaybackEngines/androidplayer/AndroidManifest.xml does not exist System.IO.File.Copy (System.String sourceFileName, System.String destFileName, Boolean overwrite) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:107) System.IO.File.Copy (System.String sourceFileName, System.String destFileName) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:86) ChartboostSDK.CBManifest.GenerateManifest () (at Assets/Chartboost/Editor/CBManifestEditor.cs:28) ChartboostSDK.CBManifest.CheckAndFixManifest () (at Assets/Chartboost/Editor/CBManifestEditor.cs:38) ChartboostSDK.ChartboostPostProcess.PostProcessBuild_Android (System.String path) (at Assets/Chartboost/Editor/CBPostProcess.cs:48) ChartboostSDK.ChartboostPostProcess.OnPostProcessBuild (BuildTarget target, System.String path) (at Assets/Chartboost/Editor/CBPostProcess.cs:36) UnityEditor.HostView:OnGUI()
