MAUI: 'Controls' could not be found and mipmap/appicon_round not found.

I am getting below errors when rebuilding the app in release mode before creating APK file.

I tried adding the appicon and appicon_round under Platforms/Android/Resources/mipmap, but no luck.

I am using Controls.UserDialogs.Maui - 1.3.0 for showing the userdialogs and due to that the last error is showing: The type or namespace name 'Controls' could not be found. I tried updating it to 1.5.0 but no luck.

My .Net version was 7 and I tried to update it to 8.

My VS(Windows) version is 17.9.0 Preview 1.0 also I tried on 17.8.1.

I tried creating a demo project with this issue, but in that there is no such issue.
