Start at DotSpatial.Controls.AppManager.CurrentDomain_AssemblyResolve and trace how GetCatalog and LoadExtensions handle assembly paths during HydroDesktop.MainApplication.MainForm startup. Reproduce the reported startup failure if possible and determine the assembly-loading input that produces the negative StartIndex. Done means startup no longer raises this ArgumentOutOfRangeException.
