The problem is quite simple. I am not able to use variable fonts installed on my system. I have attached screenshots showing that my computer properly recognizes the font however, none of the programs, Photo 2, Designer 2, Publisher 2, correctly recognise my font. And yes, this is the case with other variable fonts as well, not just one. Fonts were downloaded from Google Fonts.
Running Windows 11 22H2. Downloaded all programs from Microsoft Store. If you need any other info, I'll be happy to provide.
P.S: Sucks to not be able to create something on the first day itself. But I guess launching a software has its share of challenges.
