cypress-angular-unit-test SocketCt#startListening must first be called before accessing 'this.io'

Current behavior

I followed the README instructions to setup Cypress component testing with Angular 12 (followed the Webpack 5 instructions).

When I execute npx cypress open-ct I get the error: SocketCt#startListening must first be called before accessing 'this.io'

$ npx cypress open-ct

Desired behavior

I would want to see the Cypress window to be able to run the new cy-spec tests

Test code to reproduce

If the code above is not enough to troubleshoot, let me know to put together a working sample. My company's project is large and confidential, so this would take time.
