Expand BalaReva.Excel.Activities - you’ll see that it has at least the UiPath.Excel.Activities and UiPath.System.Activities inside it. Mouse over to see what version was requested and what was resolved. These versions will conflict with your top level Excel and System packages, and nuget will resolve these conflicts based on certain rules.
You could try just deleting your Excel and System Activities dependencies so it’ll just use whatever is in BalaReva.
You should read this as it explains how dependencies are managed, and how conflicts are resolved.
