Are you including the enum header inside of your actor where you are declaring the property?

If you made the header file with the enum by hand then check if it’s in the source folder. VS sometimes puts fresh files in the intermediate folder for some reason.
Make sure the enum header file is visible in your solution explorer in the project.

From the error it also seems to point to a variable called offsetof that is already a built in reserved work. Try changing the your variable name if it is present.

The structure of the enum itself works fine. Tried it in a test project and everything compiles no problems. Try checking your includes.

Thanks, It worked after including the ENUM Header in the Header file instead of cpp file
