First Build Successful but Now Getting Errors every time for the same app

Unity Engine

I built an app bundle for android app, after uploading it to play console It told me that 64 bit isnt supported so I changed the player settings and tried to build a new bundle for the same app - tried 6 times and get the same 3 errors every time - I have not changed anything except for the Scripting Backend Config and the Target Architechtures.

UnityEditor.BuildPlayerWindow+BuildMethodException: 3 errors

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr) (at /Users/builduser/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:187)

The errors should be in other lines. This only states the fact.

You have a platform invoke method _sendMessageOther which is not implemented for Android, either provide the method, or don’t call this function, by wrapping the code #if !UNITY_ANDROID
