Hi Jayant,

Thank you for reaching out.

We attempted to replicate the issue by loading a PDF with link annotations in version 31.1.23, based on the stack trace details you provided. However, we were unable to reproduce the reported issue, “PDF Viewer crashes when loading the PDF in version 31.2.3.”

We suspect that the problem might be specific to the document. Could you please share the PDF file where the issue occurs? Additionally, kindly confirm whether the issue persists in the latest version 31.2.10. If it still occurs, please provide the steps to replicate the issue so we can investigate further.

Regards,

Bharathi S
