Failed to execute 'define' on 'CustomElementRegistry' when using ClarityIcons

In my application I want to use ClarityIcons.add() to add a custom icon. However I get the following error:

index.js:402 Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': this name has already been used with this registry
    at Object../src/clr-icons/index.ts (http://localhost:4200/vendor.js:84958:20)

    at Module../src/app/app.module.ts (http://localhost:4200/main.js:618:94)

I tried reproducing it in a stackblitz but there it worked fine. In other questions I read about deleting the package-lock.json and then reinstalling node modules. I tried this but I still have the same result. Any idea where the error could be?

It looks like you are somehow including Clarity Icons twice in your app. Typically, this can happen if you include the pre-compiled clr-icons.min.js and also bundle the icons library as part of your own JS bundle.

Since you call ClarityIcons.add(), I'm guessing you import { ClarityIcons } from "@clr/icons";. If you do this, you want to remove clr-icons.min.js from your index.html and follow the "Load Clarity Icons API and icon sets in Typescript" section in the documentation: https://vmware.github.io/clarity/icons/clarity-icons
