Crystal Report- Please wait while the document is being processed

Question

Highlights

→ Recently Upgraded from VS2008 (Integrated Crystal Report) to VS2022.
→ VS2022 auto upgraded Crystal Report 2008 to Crystal Report SP33 for VS2022 (installed manually).

Problem

All reports are working as before except one Crystal Report. It shows the below message.

Error: Please wait while the document is being processed.

Even after 30 min of waiting the error persists.

BUT

If instead of displaying i directly print it then there is no problem.
STRANGE!!!!

Things I have Tried

1. Tried removing one field at a time.
   Result: Error persists
2. Tried removing all fields in the report and leaving the report blank.
   Result: Error persists
3. Tried removing database from the report and removing all the older fields and leaving the report blank.
   Result: Error persists
4. Youtube Solution which says check version in registry under

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Crystal Reports

and check if CRRuntime32Version and CRRuntimeMSMVersion has same Crystal Report version under it.
Result: I only have CRRuntime32Version Key available in it and it has right version written in it 13.0.33

Need Help

Reconstructing the Crystal Report is the last option but will take so much time as this is a legacy code. Please let me know if you have come across solution for such a problem.

Edit 1

Code for Crystal Report displaying

ReportDocument Rpt = new ReportDocument();
Rpt = new Forms.Printing.Rpt_Sales();
Rpt.PrintOptions.PaperSource = CrystalDecisions.Shared.PaperSource.Auto;
Rpt.Refresh();

crystalReportViewer2.ReportSource = Rpt;
crystalReportViewer2.Refresh();

For the moment removed DataSource as no fields are present. Still the error persists.
