Just by looking at the error, it indicates that Visual Studio 2022 is installed but missing the C++ toolchain required for building Unreal Engine projects?
To resolve this, you need to ensure that the necessary components are installed in Visual Studio 2022.

Make sure you have the following things installed:

  1. MSVC VS 2022 C++ x64/x86 build tools (Latest)
  2. Windows 10 SDK (10.0.19041.0 or later)
  3. C++ CMake tools for Windows
