In certain UE 5.5 projects where C++ code is added to a Blueprint project or a fresh C++ project is created, the Game target build succeeds and populates the Binaries\Win64 folder with executables and DLLs, yet the Editor build appears to compile without error while producing no output in the Binaries\Win64 directory. As a result, when opening the UE 5.5 Editor, the following error is displayed: “The following modules are missing or built with a different engine version: [module name]”. The Unreal Build Tool (UBT) log further reports an error stating, “Expecting to find a type to be declared in a module rules named ‘VisualStudioTools’ in ‘UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’. This type must derive from the ‘ModuleRules’ type defined by UnrealBuildTool.” This issue was resolved by copying the VisualStudioTools plugin from the Plugins directory into the Plugins\Marketplace folder, ensuring that the proper module rules are recognized and the Editor output is correctly generated.
