Aspose.Tasks crashing when opening Project file

Hi Aspose team,

when trying to open Project file (very simple file) with Aspose.Tasks 18.8 I am getting following error:

Message=Project reading exception.
at . ​ (Project , Stream )
at .(Stream )
at Aspose.Tasks.Project.(Stream , ParseErrorCallback , PrimaveraXmlReadingOptions )
at Aspose.Tasks.Project…ctor(String projectTemplate, ParseErrorCallback parseErrorHandler)
at Aspose.Tasks.Project…ctor(String projectTemplate)
at AsposeTasks.AsposeTasks.OpenProject() in C:_Projects\Bugs\Aspose\0\Aspose.Bugs\Project.cs:line 42
at ReplaceTextInSinglePageOfPDF.Program.Main(String[] args) in C:_Projects\Bugs\Aspose\0\Aspose.Bugs\Program.cs:line 91

Inner Exception 1:
ArgumentException: An entry with the same key already exists.

Test project and file are attached.

Can you please investigate?

as I see that this issue is resolved does that mean that fix will be available with next release of Tasks?
