Do you have any aliases configured in tsconfig.json ?

    "baseUrl": "./src",
    "paths": {
      "@app/*": [ "app/*" ],
      "@assets/*": [ "assets/*" ],
      "@env": [ "environments/environment" ],
      "@pages/*": [ "pages/*" ],
      "@services/*": [ "services/*" ],
      "@theme/*": [ "theme/*" ]
    }
