Named destination sometimes won't work from CMD

[Flock3]

Reproduce:
Add a named Destination to a PDF(created by MsWord ) via Ghostscript

gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=./out.pdf ./in.pdf ./pdfmarks.txt

From Windows CMD run:

"C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe" /A "nameddest=Test" out.pdf

After some tries I always get an File open error, same cmdline works on a second try, see gif attached.

Info:Win10 x64 Adobe ReaderDC Ver 2020.013.20074 -> See Systemreport attached

It seems to me that theres some kind of filehandel problem
