visual studio provider errors with use of field keyword - when typing

[UniqeId6542]

Version Used:
Visual Studio 17.12.0
c# project with language preview enabled

Steps to Reproduce:

1. In a type in:

    private string? foo = null;
    public string Foo
    {
        get
        {
            if (this.foo is null)
            {
                FieldInfo field = typeof(String).GetField(nameof(string.Length), BindingFlags.Public | BindingFlags.Instance)!;
                this.foo = field.GetValue("hi");
            }

            return this.foo;
        }
    }

2. When typeing in the field.GetValue part, many provider errors are produced by Visual Studio

Expected Behavior:
no provider errors

Actual Behavior:
The call stack of all of them looks similar enough that I'll only include one.

The exception occurs creating a SpeculativeSemanticModel and using a field reference within an accessor that does not use field. See #75398.
