Errors during project compilation related to the "Animation" plugin

Do your custom classes use the API macro to isolate the variables

UCLASS()
class MYPROJECTNAME_API AMyActor : public AActor
{
// my code
}

You can also isolate parts directly via namespace

XXX_API macro for namespaces (exposing plugin namespace function)

You put the macro before the function signature in the declaration. namespace MyNamespace { XXX_API void MyFunc(); }
