Bug Report related to LibreOffice Writer Crashing
Bug Summary: Writer crashes when opening .docx created by RootsMagic

Version: 25.2.2.2 (X86_64) / LibreOffice Community
Build ID: 7370d4be9e3cf6031a51beef54ff3bda878e3fac
CPU threads: 12; OS: Windows 10 X86_64 (10.0 build 19045); UI render: Skia/Raster; VCL: win
Locale: en-US (en_US); UI: en-US
Calc: threaded

Bug Description: RootsMagic is a popular genealogical software program which allows its users to create a wide array of reports and then optionally write to different formats including .docx. The problem presents itself when LibreOffice attempts to open the .docx file created by RootsMagic. No other word processing programs are known to crash when opening a .docx file produced by RootsMagic, only LibreOffice. Much more detail is discussed in this thread: https://community.rootsmagic.com/t/rm10-publish-narrative-save-docx-why-is-libreoffice-crashing/13705
