Server gets down while converting some .DOCX and .PDF files to PDF

Hello Syncfusion ,

This is Ganesh Divekar and using the licensed Syncfusion toolkit.
Recently, our clients have been facing an issue while converting specific (.DOCX)  and (.PDF) files to the PDF.
Whenever  a User tries to convert these files to the PDF it takes server down (it reaches maximum cpu utilization) and it stops waiting on the highlighted line of code below.

Please find the attached zip file.

DocToPDFConverter converter = new DocToPDFConverter();
pdfDoc = converter.ConvertToPDF(filePath);
