Sorry to hear about the problems loading the Gutenberg controls Shirley, our team will do everything we can to help!
The problem you described can be related to a number of things. The first step I recommend is making sure all of your plugins, themes and core files are updated to their latest version to see if any of the recent updates fixes the issue with the controls not loading as expected.
I also suggest making a backup of your website before running any of these updates in the unlikely event that something happens during the update process. That way, you will have something to restore from should any issues occur. If you do not already have a backup solution for your website you could try out our WordPress backup plugin Total Upkeep to quickly generate website backups right through your WordPress dashboard.
If the updates do not fix the problem, or there are no available updates to run, then the problem could be happening because of a plugin conflict. You can test for a plugin conflict by temporarily deactivating all of the plugins installed on your website and then checking the editor to see if the controls start working. If the Gutenberg controls are functioning without any plugins active then start reactivating each of the plugins one by one to see which is responsible for the conflict.
Please let us know if there is anything else that we can do to help Shirley!
