@guavaman Thank you for the quick and fast support! Sorry this is such a frustrating bug. I’ve gone ahead and uninstalled Visual Studio 2019 for the time being - however I actually ran into a few issues downgrading. The Windows SDK in the registry was set to an incorrect version - I followed this post and was just able to do a build without issues: Cannot build with ILC2PP in 2019.1.8f1
Going to do a few tests again with 2019 using this SDK and will let you if I have any success.
