Bug- Acrobat PDF Form document with digital signature fields does not launch
Since Friday, November 17th, 2017, we cannot open adobe acrobat form documents that contains digital signature fields. When we try to open the document, Adobe Acrobat application is not responding. First, I thought it is about verifying the digital signatures but even the unsigned form cannot be open. Also same document that digitally signed before cannot be open.
I created this form using Adobe Acrobat Pro DC in April 2017. It was working fine until November 17th, 2017. All our users have same problem.
OS: Windows 10 Pro Ver: 1703 Build: 15063.0
Adobe Acrobat Pro DC, Continuous Release | Version: 2018.009.20044, File Version: 18.009.20044.55097, AGM Version: 4.030.00072, Cool Type Version: 5.014.00025, Core Version: 18.2304, JP2K Version: 1.002.00002.39492
I posted this problem on Adobe Forums on November 21. George Johnson, MVP & Adobe Community Professional said that it could be related to recent Adobe update. https://forums.adobe.com/thread/2414422
Please fix this bug.

Seems to be a problem with the form itself as the unsigned form also does not open .
