Activating the plugin automatically takes away admin privileges

I have installed the plugin and activated it on appengine. However, I see that I no longer have site administrator privileges; I can no longer install or access any edit pages through wp-admin after activation. De-activating the plugin automatically re-enables my ability to edit pages and install themes etc.

I suspect this might have to do with the bucket storage settings, but I can’t tell for sure. For the cloud storage bucket I created for this purpose, I set the user account privileges to “Writer” and the user account email to that of my appengine application.

Thanks
