Installed OTF font not displaying

Hey all. I have a normal OTF typeface from a known font designer. After I install it, it shows in my Character panel, but there is no preview and nothing shows when I use it. It's just...blank/no characters. E.g. I can type my words in another font, but when I swap to this font, it's just a blank box. I tested it in Microsoft Word and it works fine. But, in Illustrator and Photoshop, it's just not displaying. It also kind of seems to mess with my artboard if I try to use it as well.

I have reached out to the designer, but have not heard back. Most of my searches for issues like this result in incorrectly installed or corrupt fonts. This is not the case. I'm so frustrated, as it's a typeface I really want to use. Thanks!
