May 19, 2024 - Interestingly, though not surprisingly, the DevTools extension uses Angular to build the UI you see in the Chrome console. You can think of this user facing part of the extension as a frontend equivalent of a browser application.

You may be missing a development configuration for your application.
In your angular.json navigate to architect -> build -> configurations and add these lines, below the definition of the production build:
"configurations": {
"production": {
// already there!
},
"development": { // this is new!
"buildOptimizer": false,
"optimization": false,
"vendorChunk": true,
"extractLicenses": false,
"sourceMap": true,
"namedChunks": true
}
},
"defaultConfiguration": "production"
And to run the build in development mode just type the next command: ng build --configuration development.

I had all of those settings and configurations in place in angular.json.
For me, the problem was the following:
main.ts:
if (environment.production) {
enableProdMode(); // <-- here
}
platformBrowserDynamic()
.bootstrapModule(AppModule)
.catch(err => console.error(err));
And apparently, I changed the production property of my environment.ts file at some point in the past, setting production in there to true, even in development mode.
Changing it back to false finally resolved this for me.

node.js - correct way to debug npm packages in angular - Stack Overflow
How exactly should I bring a script which comes somewhere under "node modules" into Chrome DevTools sources tab so that I can debug it? I have tried using npm link and adding the script to the "assets" section under options in build, but it didn't work for me.
