Hello
I add C++ class in my project and now I can’t open c++ project.
I use UE 5.6.1 and Visual Studio 2022 (version 17.14.15).

I don’t know this problem is a bug come from my project or the Unreal Engine version I use.

If this bug come from to my project how to resolve this problem?

Here is errors when I build my project in Visual Studio:

Unable to find ‘class’, ‘delegate’, ‘enum’, or ‘struct’ with name ‘UStateTreeAIComponent’
The command ““C:\Program Files\Epic Games\UE_5.6\Engine\Build\BatchFiles\Build.bat” MyProjectEditor Win64 DebugGame -Project=“C:\Users\diane\Documents\Unreal Projects\MyProject\MyProject.uproject” -WaitMutex -FromMsBuild -architecture=x64” exited with code 6.
