Does this issue occur when all extensions are disabled?: Yes.

In the fact, this problem is not encountered in actual use, but a bug encountered when I tried to modify VS Code.

• VS Code Version: 1.73.0 be022da
• OS Version: Macos 12.2.1 Intel

Steps to Reproduce:

1. Clone VS Code source code
2. yarn install
3. Add dependencies to remote/web/package.json.For example, add react-dom to simulate scenarios where dependencies need to be added to vscode-web., then yarn add react-dom under the root directory.
4. Use cmd + shift + B shortcut keys to perform Core - Build and Ext - Build tasks. Then you will find that the mission unexpectedly quit.

5. The problem is that browser fields can be not only string but also objects.
