# SharedArrayBuffer error with 3.6.4 and block editor

 * After updating to version 3.6.4, we are no longer able to use the block editor
   to update the Appearance > Widgets page within our Dashboard. Any change results
   in a SharedArrayBuffer error, forcing us to disable the plugin any time we need
   to make changes to the widgets. Hoping to see a resolution for this in an upcoming
   release.

 * Unfortunately, the issue is not resolved and we can only update the widgets when
   we completely disable the WordPress REST API Authentication plugin.
