Gutenberg Controls Working But Show As Blank

Hi! I’ve been using the Gutenberg editor on my site but I have to guess at what the buttons do, as they are showing blank. They work as intended, but I can’t see them. At first, I thought this was a plugin or theme issue. I have removed ALL plugins and switched to 2019 Theme, but the problem persists.

The link above is to a screen shot of the blank Gutenberg controls when I’m editing a post.

My website is https://home3dprints.com. My host is SiteGround.
