Start with DotSpatial.Plugins.ExtensionManager.ExtensionManagerForm.ShowInstalledItemsBasedOnSelectedCategory and the DataProviderCategory path in the stack trace, then inspect DotSpatial.Data.Rasters.GdalExtension.GdalHelper and GdalRasterProvider. Reproduce the failure by selecting Data Providers in the Installed Extensions tab and trace the missing gdal_csharp dependency. Done means the category opens without an unhandled composition exception.
