The error you're encountering indicates that the SpineUE.h file is missing, which suggests that the project setup might be incomplete or incorrect. Ensure that you have correctly cloned the spine-runtimes repository and copied the necessary spine-cpp and spine-ue plugin files into your project. After doing so, regenerate the Visual Studio project files by right-clicking the .uproject file and selecting "Generate Visual Studio project files." Then, open the .sln file in Visual Studio and build the solution. Make sure you are using the latest version of the spine-runtimes and that your Visual Studio setup is correctly configured to include all necessary paths.
