Cannot find the duplicate identifier that the compiler finds.

We have the following class definition: 

export class RegistrationForm {  

}

The Visual Studio Code errors and warnings panel says:

[ts] Duplicate identifier 'RegistrationForm'. src/registration-form.ts(1,14)

[ts] Duplicate identifier 'RegistrationForm'. src/registration-form.ts(2,15)

Here is the screenshot:

Duplicate identifier.

We have done a Find in Files and found no other declarations of RegistrationForm.

Why is TypeScript complaining about a duplicate identifier that doesn't exist? How do we resolve this?

Suspect its an issue in tssserver. You probably have two tsconfig.json files and this file is somehow (due to a failed path uniqueness check) getting included twice.

To be sure its not a compiler error and just an IDE error you can run tsc on the command line or give another IDE a go (e.g. http://alm.tools/ 🌹)
