Description:
Libre Office portable starts to crash on Windows Server Core 1903 or newer (both Hyper-V and run as docker image). After crash I didn't see any logfile, also eventlog was empty.


Libre Office works correctly only on Windows Server Core version LTSC - 1809.


Easiest way to reproduce this error is to run LibreOffice as docker image and run convert operation. I described whole procedure in "Steps to reproduce" section.

Steps to Reproduce:
1. Install "Docker Desktop for Windows" on Windows 1903 or higher

2. Intall LibreOffice portable to "C:\LibreTmp\Libre7" ; create file "C:\LibreTmp\sample.docx" (sample file to convert)

3. Run "Windows Server Core 1903" container in "interactive mode" with mounted tmp folder: 

   C:\> docker run -it --entrypoint powershell -v "C:\LibreTmp\:C:\LibreTmp" mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-1903

3. Run conversion for any document (in my case I used "sample.docx" and convert it to pdf) in container:

   C:\> mkdir c:\user\env
   C:\> mkdir c:\user\profile
   C:\> $env:USERPROFILE = "C:\user\profile"
   C:\> Start-Process "C:\LibreTmp\App\libreoffice\program\soffice.exe" -argumentlist "--convert-to pdf --outdir C:\LibreTmp\ C:\LibreTmp\sample.docx" -wait
   C:\> dir C:\LibreTmp\

4. As a result there is no converted document (c:\LibreTmp\sample.pdf) because Libre Office crashed in strange way..

5. Exit and shutdown container

   C:\> exit 


If you run above operations using "Windows Server Core 1809" container everything will work perfectly. To check just change step "3" to:

   C:\>  docker run -it --entrypoint powershell -v "C:\LibreTmp\:C:\LibreTmp" mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019


Actual Results:
Libre Office crashed, there is no converted document

Expected Results:
there is converted document as result of operation.


Reproducible: Always

Additional Info:
LibreOffice crashed without any logfile..
