The ouput docx is still bad.
The output file can not be loaded with Aspose.words for .net 24.3.

Tested OSs were Win7 and Win10
.NET target platform is .net 6.0
Using SDK: Aspose.PDF for .Net 24.3

Testing code

void ConvertPDFtoWordDocAdvanced(string filename)
{
    var pdfFile = filename;
    var docFile = filename + ".docx";
    Document pdfDocument = new Document(pdfFile);
    DocSaveOptions saveOptions = new DocSaveOptions
    {
        Format = DocSaveOptions.DocFormat.DocX,
        // Set the recognition mode as Flow
        Mode = DocSaveOptions.RecognitionMode.Flow,
    };
    pdfDocument.Save(docFile, saveOptions);
}

It seems RecognitionMode.Textbox works well.

We have tested using below code snippet and could not replicate the issue. Below is the code snippet that we tried. Please check it and let us if we missed anything.

Document pdfDocument = new Document(dataDir + @"工程项目施工的成本控制 80p-45.pdf");

DocSaveOptions saveOptions = new DocSaveOptions();
saveOptions.Format = DocSaveOptions.DocFormat.DocX;
saveOptions.Mode = DocSaveOptions.RecognitionMode.Flow;
//saveOptions.RelativeHorizontalProximity = 2.5f;
//saveOptions.RecognizeBullets = true;
pdfDocument.Save(dataDir + "工程项目施工的成本控制 80p-45.docx", saveOptions);

Aspose.Words.Document wordDocument = new Words.Document(dataDir + "工程项目施工的成本控制 80p-45.docx");
wordDocument.Save(dataDir + "finaldocument.docx");

@kngstr @asad.ali The problem is not in Aspose.Words. The DOCX document produced by Aspose.PDF is not valid. MS Word also cannot open DOCX document produced by Aspose.PDF. The exception message clearly shows what the problem is. MS Word allows maximum 63 columns in the table. So I move the topic back to Aspose.PDF form for further handling.
Input PDF: 工程项目施工的成本控制 80p-45.pdf (344.8 KB)
DOCX produced by Aspose.PDF: tmp.docx (57.3 KB)

Code:

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(@"C:\Temp\in.pdf");

Aspose.Pdf.DocSaveOptions saveOptions = new Aspose.Pdf.DocSaveOptions();
saveOptions.Format = Aspose.Pdf.DocSaveOptions.DocFormat.DocX;
saveOptions.Mode = Aspose.Pdf.DocSaveOptions.RecognitionMode.Flow;
pdfDocument.Save(@"C:\Temp\tmp.docx", saveOptions);

Aspose.Words.Document wordDocument = new Aspose.Words.Document(@"C:\Temp\tmp.docx");
wordDocument.Save(@"C:\Temp\out.docx");

@alexey.noskov

You are right. I tested it with older version of Aspose.Words and it did not throw any exception on my end. Also, the generated DOCX by Aspose.PDF was opened in WPS which also did not show any error and displayed the file correctly. Nevertheless, the details have been logged with the ticket for review.
