After upgrade to macOS Monterey and Xcode 13.1 my C++ projects are failing to compile. There are a lot of errors for not defined entities in various headers and a lot of linker errors for header files not found. This situation appeared after the upgrade with absolutely no changes in the codebase of my projects. Before the upgrade everything was fine and now I have more than 20 errors in one of my projects! I'm using VS Code as an IDE. Please give me advice, how to fix this issue?
