Windows 11, Visual Studio 2019, Program is the wxwidgets example of hello world.
It compiles and runs in debug mode.
Switch to Release and the first line of code immediately has the red squiggles.
Line 03 is
#include <wx/wxprec.h>
The squiggles toggle on and off as the mode is switched between Release and Debug.
Aside from the red squiggles did you receive actual error messages from the compiler? If so, what were they?
Perhaps VS2019 was not properly configured for use with wxwidgets.

Presumably you've got different include directory settings (and probably other settings too) between your debug & release configurations.
The third line is:
#include <wx/wxprec.h>
The error code is:
1>E:\CODE\WX\wxwidget_01\wxwidget_01.cpp(3,10): fatal error C1083: Cannot open include file: 'wx/wxprec.h': No such file or directory
Once it gets there, the remainder is obviously hopeless.
The first two lines are comments, the third is the first line of code, and it errors out there.
But as noted, it compiles in Debug.
I am almost a novice with VS 2019.
Thanks for the link to wxwidgets.org
