Errors coming from untouched UE5 source files

Development Programming & Scripting

I have these errors from files that I have not made any changed to.

  • I have tried regenerating Visual Studio files.
  • I also uninstalled/reinstalled Unreal engine and Visual Studio.
  • I originally started with Visual Studio 2019 but when I started getting these issues, I did update to Visual Studio 2022.
  • One post I found said the issue was resolved by going to the Visual Studio Installer → Visual Study Community 2022 → Modify - Individual Components → uncheck IDE Support for Unreal Engine. but this did not resolve it for me
  • Another post suggested Click Edit → Editor Preferences → Source Code Change Source Code Editor to “Visual Studio 2022” Click Tools → Refresh Visual Studio 2022 Project Click Tools → Open Visual Studio 2022 to open the project in Visual Studio
  • I have tried opening various UE5 projects but the errors persist even when no code/classes have been added.

I’m lost in this dark world any help is appreciated!

After I Rebuild (instead of Build), this error goes away.
Note that in order to build in vs, you have to close UE editor first

Greetings @ZNNS

Welcome to the Unreal Engine Forums! In regards to the error posted above, I presume you’re getting the same ‘VisualStudioToolsCommandlet looked like a commandlet, but we could not find the class’ error. I’d recommend taking a look at this post. There were some users there experiencing the same problem. Let me know if this helps with your issue!
