Uncaught (in promise), Can't read configurator when opening new angular project


I’m trying to create a new angular project.

I did ng new routing-app --routing --defaults to create the project. It didn’t ask for css/sass/… such as before. I can run the project with ng serve.

When I open my website (without creating something), I get this error :

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'configurator')
    at testerMaker.js:1
    at c (testerMaker.js:1)
    at Generator._invoke (testerMaker.js:1)
    at Generator.next (testerMaker.js:1)
    at w (testerMaker.js:1)
    at r (testerMaker.js:1)

So I can fix it by myself because it’s from an unknow ts file.

The issue is that routing failed. It always show main page only

ng version output:

Angular CLI: 12.2.9
Node: 12.16.1
Package Manager: npm 8.0.0

@angular-devkit/architect       0.1202.9
@angular-devkit/build-angular   12.2.9
@angular-devkit/core            12.2.9
@angular-devkit/schematics      12.2.9
@schematics/angular             12.2.9
ng-packagr                      12.2.3
rxjs                            6.6.7
typescript                      4.3.5


I report this in angular-cli.

They suggested to check in incognito mode : No error.

I check which extension was creating this issue, and on which site.

I found that wanteeed create the issue everywhere (just, for other website I didn’t see it). So, to fix this issue, I just remove the extension.
