Build error on UE5.3 branch

@Tadinu Thank you for your support on UE 5.3! During compilation using the UE5.3 branch, the following error occurs.

If I remove the constexpr keyword, it compiles fine. Any suggestion?

Hi, pls make sure you use rclUE's 5.2 branch for this & have added CppStandard = CppStandardVersion.Latest; in all of .Build.cs including project & plugins
