Nullability of reference types in type of parameter 'sender' of 'void MainWindow.GlobalHookMouseDownExt(object sender, MouseEventExtArgs e)' doesn't match the target delegate 'EventHandler<MouseEventExtArgs>' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'sender' of 'void MainWindow.GlobalHookMouseUpExt(object sender, MouseEventExtArgs e)' doesn't match the target delegate 'EventHandler<MouseEventExtArgs>' (possibly because of nullability attributes).
