Function Evaluation Timeout Exception on pdfDocument Page ColorType

We got a issue while processing PDF though Aspose components.

Version used: 20.5.0.0

I need to extract table data from pdf, while implementation I used TableAbsorber, but TableList.Count is shown 0,

While debugging I have identified that

pdfDocument.Pages[i].ColorType
Shows exception "function evaluation timeout"

Please advise how to get rid of this exception, as it’s very critical at this moment. I already spend more time on this for search and all.

This is the ASPOSE version info.
And sample code snippet.

        List<Filing> filingList = new List<Filing>();
        MainModel model = new MainModel();
        string _FileName = "";
        try

                HttpPostedFileBase file = files[0];
