Access Violation in Acrobat.dll with Acrobat Pro DC November 2020 Release

[23asde]

I'm experiencing the occasional crash while opening the pdf file in our software which use adobe dll with the lastest Acrobat Pro DC.  There's no issue before 11/03/2020 Acrobat release.  

So I believe it was caused by the lastest Acrobat Release.  

The attachments are the crash log that contains the call stack information and Exception Record screenshot.   

The exception code is 3221225477 - Access Violation.
