4. Observe the console and network tabs for errors.

I'm here to help out the maintainers and am going to see if I can fix the issue or at least get close enough to be helpful! I'll investigate the webview resource loading errors (ERR_ACCESS_DENIED and 404 errors) and work on a solution.

[roomote]

I've created a pull request to fix this issue: #6685

The fix addresses both the ERR_ACCESS_DENIED errors for JavaScript chunks and the 404 errors for source maps by:

1. Removing 'strict-dynamic' from the Content Security Policy to allow dynamically loaded chunks
2. Creating compatibility source map files that the webview expects (index.map.json and index.sourcemap)

The changes have been tested locally and all tests are passing. The PR is currently going through CI checks.
