Document comparison crashes when comparing documents with bullet lists with specific styling


We have two versions of an MS Word document that cause a crash when compared with GroupDocs.Comparison. The documents have a bullet list with a style called “Bullet list”. The style has the same name in both documents, but the settings for the style differs. If I change the style of the bullet list the comparison works as expected.

SOP18.docx (105.4 KB)
SOP28.docx (105.2 KB)

I get the following exception details when comparing the documents:

Message=Error occurred while converting document.
 at .(List`1 , CompareOptions ,  ,  , Int32 )
 at .(Int32 )
 at .()
 at .SaveDocument(Stream , Document , Document , SaveOptions )
 at GroupDocs.Comparison.Comparer.(Stream , SaveOptions )
 at GroupDocs.Comparison.Comparer.Compare(Stream document, SaveOptions saveOptions, CompareOptions compareOptions)

The exception was caused by running the following code with GroupDocs.Comparison 24.1.0 in a .NET 6.0 console application on a Windows 11 machine:

using var comparer = new Comparer(loadPath1);

We get no results when comparing the same documents in the online tool:

I suppose this is because of the same crash
