The project could not be compiled. Would you like to open it in Visual Studio?

I’m having the same issue. Looking into it and I’ll let you know what kind of solution I come up with :slight_smile:

edit: posted answer.

Looks like in 4.8 something was changed with TEnumAsByte where you cannot use it as a reference in a function parameter. From my brief look, it seems to be occurring in the generated areas.

Solution:

Change all function parameters that use a referenced TEnumAsByte to a value TEnumAsByte.

Example: TEnumAsByte& to TEnumAsByte.

This worked for me! :slight_smile:

Best of luck!
