I am suddenly getting an odd Plugin error in Simhub. What could be the issue and how to fix it?

This is from the error log.

INFO - Loading plugins controls
ERROR - An error occured while loading plugin settings control for Gary Swallow Plugin: System.ArgumentNullException: Value cannot be null.
Parameter name: input
at System.Text.RegularExpressions.Regex.Replace(String input, String replacement)
at System.Text.RegularExpressions.Regex.Replace(String input, String pattern, String replacement)
at GarySwallow.PluginSdk.SettingsControl..ctor()
at GarySwallow.PluginSdk.GarySwallowDataPlugin.GetWPFSettingsControl(PluginManager pluginManager)
at SimHubWPF.MainWindow.LoadPluginsControls()

The only thing that changed in my system is a new wheelbase.

Best,

David
