In Acrobat OLE of DC2021, when I call a PDF with hundreds of pages with getPageNthWord function of JSObject, it stops at an unspecified page and word number.

The arguments of this function specify the correct page and word number, and the code works fine in DC2017.

The place to freeze is not the same every time, and the pattern is not fixed.

I have the following questions about this issue:

Is there a way for the calling program to fix this bug?

It's working fine in DC2017, so I think it's a bug specific to DC2021, but is the manufacturer aware of this issue?

End users are automatically upgraded to DC2021, but is there a way to revert to DC2017 or not upgrade to DC2021 until the issue is resolved?

Thank you for reading.
