Currency structure occurs CS0188 error in TargetFramework net6.0 or greater

[s2quake]

The detailed message of the CS0188 error is shown below

error CS0188: The 'this' object cannot be used before all of its fields have been assigned.

In the Currency struct constructor, it uses a local method called GetHash to set a value in a field called Hash. This violates the rule described above. I think the problem would be solved if the field Hash didn't need to be defined, but rather calculated and used as needed.

        public Currency(IValue serialized)
        {
            ...
            Hash = GetHash(); // CS0188 error
        }
