Cannot Insert a Photo on a Web Page

I am trying to insert a photo onto this webpage: https://www.brcdenver.com/New-Home-Specialist-
When I click on the photo icon, nothing happens.
What is causing this to not work?
Thank you for any help you can provide.

Can you try again to see if the issue is still there?

I am able to access the Images and Files Manager by 1 - clicking on the photo icon directly

or 2 - go to the Insert > Image > You can either enter the image URL or click the photo icon here

When you select and place an image on your webpage, you can also drag the corner of your file to resize it.
