After updating to Magento 2.3.0 from 2.2.6, I am unable to access the Design Configuration - Global View page. When I open the page, the GIF Spinner keeps rotating, but the page never fully loads.

Checking the console log, I can see the following error:

VM1667:2 Uncaught ReferenceError: Base64 is not defined

This is what worked for me: https://github.com/magento/magento2/issues/19549#issuecomment-447327672

To test, I first made the edit only in the file 'vendor/magento/module-theme/view/adminhtml/ui_component/design_config_form.xml', and it worked!

Seems to be a bug, which will be patched in Magento 2.3.1 release.

Other vendor(moduel-catalog , module-email , module-ui) don't override when it required then after change

To test, I first made the edit only in the file 'vendor/magento/module-theme/view/adminhtml/ui_component/design_config_form.xml',

find formElement="fileUploader" and replace with formElement="imageUploader"

and it worked!

Seems to be a bug, which will be patched in Magento 2.3.1 and 2.3.0 release.
