A little more info. When I look at the Project | Properties | VC++ Directories I see that the “include directories” on my desktop (where intellisense is not working well) shows the following includes added “…..\Source;…\Source\Test\Private;…..\Source\Test\Public;” whereas on my laptop these directories are not included. If I delete them from my desktop VS2022, of course then the include <> no longer finds any of my files and the include “” intellisense remains broken. I’m not sure why the include directories being added are so different. It must be that the intellisense configuration is broken somehow but just on my desktop (again both laptop and desktop using Unreal 5.3.1)
What’s strange is that if I make a non-unreal test project with my desktop with a header file in a subfolder, and I type include " then the public directory is shown in intellisense and I can navigate to my file. Oddly, there will be a squiggle underneath saying “cannot open source file /public/MyClass.h” but it will build and compile just fine. The include directories in that project is simply “$(VC_IncludePath);$(WindowsSDK_IncludePath);”
Not sure how to fix it from here. Hopefully someone more knowledgeable will chime in
