This issue was arising when we added a 'record' struct in a .cs file at the bottom of the class.

CSC : warning AD0001: Analyzer 'StyleCop.Analyzers.OrderingRules.SA1201ElementsMustAppearInTheCorrectOrder' threw an
exception of type 'System.Collections.Generic.KeyNotFoundException' with message 'The given key was not present in the
dictionary.'.

Repro issue:

public class FooClass {

...
public List Value {get; set;}
...

public record BarClass([property: JsonProperty("name") string name]);
}

No other indication was given that this was an issue. It was fixed by moving the record above the constructor of the Foo class.

I do not need further assistance; this is merely to assist others if they run into a similar issue.
