Developer Portal blank screen after login — /api/user/settings returns 500

Hello everyone,

I’m encountering a problem when accessing the DocuSign Developer Portal:

- URL: https://developers.docusign.com/platform/account/  
- After logging in, the page stays completely blank (only the header appears).
- In DevTools Network tab, the request to `/api/user/settings` returns HTTP 500.
- On the console, I see the error:
    TypeError: Cannot read properties of undefined (reading 'account_name')

Steps already tried:
- Tested in Chrome and Edge (both latest versions).
- Cleared cache and cookies, used incognito mode.
- Tried on different networks and devices.
- Extensions like AdBlock are not the root cause.

It seems the frontend cannot proceed without user settings.  
Has anyone experienced something similar? Any workaround, or is there a direct way to reset or repair account settings?

Thank you for your help!
