Application error after upgrade build Windows 10 from 1709 to 1909

Hi,
after the build update (from 1709 to 1909) when I go to print more than one PDF file in sequence, I get the error

Application name that generated the error: AcroRd32.exe, version: 20.6.20042.43423, timestamp : 0x5e616a22 Name of the module that generated the error: ntdll.dll, version: 10.0.18362.1139, timestamp: 0x335bbdaf Exception code: 0xc0000409

I have tryed to upgrade Acrobat DC on the latest version but doesn't works. I heve tryed to disable protection mode but nothing.

The same print works fine with 1709 but not on 1909. I have tryed in about 100 clients but the problem is the same

Someone have some ideas?

Thanks

Emiliano
