Current workaround : p.SomeFunc() & someTernary != 0

I'd say we also have something going on that is similar on this linq line :
.Where(p => p.SomeFunc().HasFlag( someTernary ))a
System.NullReferenceException: Object reference not set to an instance of an object.

We have a seemingly related issue we're seeing with the use of HasFlag and il2cpp. Using 2021.3.15f1.
