Aspose.Words for .NET - System.InvalidOperationException: Inaccessible because font is defined by theme font

Aspose.Words Product Family

Good evening,
I have version 19.10.0 of Aspose.Words for .NET, and today for the first time I had a very important problem, I discovered that I can never save a DOCX document created or copied or formed by merging multiple DOCX files. I always get the same error:
System.InvalidOperationException: Inaccessible because font is defined by theme font
And this prevents me from saving the DOCX file on the server.
How come it doesn’t work? To this day I have never noticed because I have always used it to save DOCX files in PDF format.
Can you please help me? I’m stuck.
Thank you

I use this command to save a simple DOCX document with another name:

dstDoc.Save(srcDoc, SaveFormat.Docx);

An update,
now i can save only one file DOCX with another name but if i append one or more file DOCX to the previous file DOCX, with this command:

dstDoc.AppendDocument(newDoc, ImportFormatMode.KeepSourceFormatting);

i recive always the same error:

System.InvalidOperationException: Inaccessible because font is defined by theme font

Can someone help me?

Thanks

I can’t update the library because my client doesn’t want to buy the updated license, I think the problem is version 19.10.0, in fact I can’t even merge PDF documents.
This is my code

// --------------------------------------------------------------------------------------------------------------------
string _elenco = _pathDocx + "elenco-richieste-pagamento.docx"
// --------------------------------------------------------------------------------------------------------------------
var _docx = Directory.EnumerateFiles(_pathDocx, "richiesta-pagamento-*.docx", SearchOption.AllDirectories);
// --------------------------------------------------------------------------------------------------------------------
// --------------------------------------------------------------------------------------------------------------------
Aspose.Words.License license = new Aspose.Words.License();
license.SetLicense("Aspose.Words.lic");
// --------------------------------------------------------------------------------------------------------------------
var output = new Aspose.Words.Document();
output.RemoveAllChildren();
Aspose.Words.Document input = null;
// --------------------------------------------------------------------------------------------------------------------
foreach (string currentFile in _docx)
{
	input = new Aspose.Words.Document(currentFile);
	output.AppendDocument(input, ImportFormatMode.KeepSourceFormatting);
}
output.Save(_elenco, SaveFormat.Docx);
// --------------------------------------------------------------------------------------------------------------------
