Strange behaviour in async method

I have a solution targeting NetCoreApp2.0.

Lately I've seen that when running an async method, the debugger shows me variables that are non allocated (out of scope).

If this variable is an IQueryable<string> it will show show up in the 'Locals window' as NullReferenceException.

If I manually set the 'next statement' to first statement in the block containing this IQueryable<string>, a NullReferenceException will be thrown when accessing the variable.
