Because the administrator has a different config file probably.
Can you find the default.conf in AppData/Codeblocks and open it in text editor and search for something like
<FONT>
<str>
<![CDATA[Fira Code Light 9]]>
</str>
</FONT>
What is the value you're using?
I built the DLL with the font patch it can be found https://github.com/stahta01/stahta01.github.io/blob/master/wxWidgets/wxmsw313u_gcc_cb.dll (https://github.com/stahta01/stahta01.github.io/blob/master/wxWidgets/wxmsw313u_gcc_cb.dll)
Build command used
mingw32-make -f makefile.gcc VENDOR=cb CXXFLAGS+="-std=c++11" MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release
Edit: I built this code https://github.com/stahta01/wxwidgets_master_fork/commits/wxwidgets3.1.3_git (https://github.com/stahta01/wxwidgets_master_fork/commits/wxwidgets3.1.3_git)
Note: I had to run this command before building.
rm -f include/wx/msw/setup.h
Edit: Built using the Compiler packaged with CB 20.03 64 bit.
