Bug Report: Stitch projects fail to load and create due to console network and JavaScript exceptions

I am experiencing a critical issue where the Google Stitch platform fails to load my existing projects (showing “Failed to load projects” in the sidebar) and fails to create any new projects (throwing “Failed to create project. Please try again later” toast notification).

Upon inspecting the Chrome Developer Console, I found several network and uncaught JavaScript runtime exceptions that prevent the application from communicating with the backend.

Console Errors:

  1. Network Error: Failed to load resource: net::ERR_CONNECTION_CLOSED for https://www.googletagmanager.com and related resources.

  2. Unhandled JavaScript Exceptions:

    • Failed to load user settings: in util-DQh63Br1.js:178

    • Failed to update user settings: in util-DQh63Br1.js:178

    • Failed to save default privacy settings: in util-DQh63Br1.js:178

    • Multiple occurrences of WIZ bundle errors: Error: gd at d9 (m=oxe1Cc:728:66) within generator promises.
