Cannot open APK file from Download folder Android C#

Question

I've Looked through all other example questions and their answers to this problem I can find to no success, I believe the issue is that the MediaProvier/Intent call cannot access the Download folder, in the device log there are MediaProvider errors stating the file path cannot be found and an EACCES permission error.

I have permissions to READ/WRITE external storage and REQUEST_INSTALL_PACKAGES persmissions

The device emulator shows 'There was a problem parsing the package' What am I doing wrong and why can I not open/install the APK file? Any help would be appreciated.

In my opinion if I was to copy the apk to a path within the internal directory rather than external then this would work, however I also cannot copy the apk to any Android/data/ location using adb due to permissions issue.

Java.IO.File path = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads);
        Java.IO.File file = new Java.IO.File(path, "test2.apk");

        // Get URI and MIME type of file
        Android.Net.Uri uri = FileProvider.GetUriForFile(context, AppInfo.PackageName + ".fileprovider", file);
        String mime = context.ContentResolver.GetType(uri);

        // Open file with user selected app
        Intent intent = new Intent();
        intent.SetAction(Intent.ActionView);
        intent.SetDataAndType(uri, mime);
        intent.AddFlags(ActivityFlags.NewTask);
        intent.AddFlags(ActivityFlags.GrantReadUriPermission);
        intent.AddFlags(ActivityFlags.GrantWriteUriPermission);
        intent.AddFlags(ActivityFlags.GrantPersistableUriPermission);
        //context.StartActivity(intent);

        Intent chooser = Intent.CreateChooser(intent, "Update");
        chooser.SetFlags(ActivityFlags.NewTask);

        IList<Android.Content.PM.ResolveInfo> resInfoList = context.PackageManager.QueryIntentActivities(chooser, Android.Content.PM.PackageInfoFlags.MatchDefaultOnly);

        foreach (Android.Content.PM.ResolveInfo resolveInfo in resInfoList)
        {
            String packageName = resolveInfo.ActivityInfo.PackageName;
            context.GrantUriPermission(packageName, uri, ActivityFlags.GrantWriteUriPermission | ActivityFlags.GrantReadUriPermission);
        }

        context.StartActivity(chooser);
