Resolution Note:
If you upgrade Burst to the latest 1.8.7 release you can see the error message clearly:
Assets\Scripts\TestRefStruct.cs(23,51): Burst error BC1064: Unsupported return type `DefaultNamespace.TestRefStruct`1<DefaultNamespace.TestStruct>` for function `DefaultNamespace.TestRefStruct`1.get_Terminating()`: structs cannot be passed to or returned from external functions in burst. To fix this issue, use a reference or pointer.
The user is returning a struct from their getter. They need to return a pointer type as that is a restriction burst applies to Burst entrypoints (they cannot pass or return structs)
