Alright, some time later with crappy Aussie wifi and the reinstall of Windows SDK and VS 2022 has worked with the .bat file, allowing the Generate Visual Studio project files option to successfully generate and regenerate.
This unfortunately still won’t recover the previous project as it still crashes on startup, my suspicion is that the corrupted structs/files will have to be identified and removed if that is possible. Or perhaps this is the start of my C++ life, who knows.
