These errors don’t ring me any bell, but every time I had issues generating the project files it was because I was missing something in the visual studio install (almost always .NET stuff), and once it was because of the BuildConfiguration.xml file (`C:\Users\Ares\AppData\Roaming\Unreal Engine\UnrealBuildTool\BuildConfiguration.xml`) that I had to edit as I explained in [this post](https://forums.unrealengine.com/t/visual-studio-2019-14-22-27905-must-be-installed-to-build-this-target/150754/4). This are the individual components that you might need to check in the Visual Studio Installer (I hid the ones that I am certain are not responsible of this issue but I have way too many engine versions installed, so something might be unnecessary to you) ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/7/2/b72c162663fd8ae504caa3ed55b40872be24f8d5.png) --- _[View the full topic](https://forums.unrealengine.com/t/please-help-me-figure-out-how-to-add-a-c-class-to-the-blueprint-project/1773948)._
