Hi Brave team,

After updating to Brave 1.77.95, I’m no longer able to use the WordPress Gutenberg editor (in wp-admin).
The editor screen fails to load properly: it shows the page title in the tab, but the content area remains blank.

Details:

*Brave version: 1.77.95 (Stable)
*Working in previous version: Yes (confirmed working in 1.71.123 portable)
*Affects: post.php and post-new.php in WordPress dashboard
*Other browsers tested: Opera and Firefox → working fine
*Observed error:

  • Failure to load admin.css from a plugin (404)
  • JavaScript crash from wp-seo-premium-redirect-notifications-gutenberg-2090.min.js
  • No editor UI rendered

I tested:

  • New Brave profile
  • Disabling all Shields and extensions
  • Private mode
  • Full cookie and storage reset

All failed in 1.77.95.
When running 1.71.123 portable, everything works perfectly.

Please advise, or let me know if there’s a regression in CSP or script execution behavior.

Thanks in advance!
