Mixing types in string interpolation causes BC1345
String interpolation works when using like types, but not when mixing.

// Burst error BC1345: Invalid argument type byte* with index 0. Only value types are supported.
Debug.Log($"{""}{0}");

Resolution Note:
This is actually as-designed. The reason the multiple-empty-strings example works is because Roslyn collapses it down to a single empty string literal. Whereas for the integer+string, the string is routed via an {{object}} parameter in {{string.Format}}, and Burst doesn't support that.
