Your documentation for embedding and/or changing Googlefonts for T3 do not match the new Joomla 4 interface. How do I change the Googlefont which come with the Kids Corner quickstart?
How to change the fonts in the Quickstart
HI railer
Here is doc for how to add font in T3 based template: https://www.t3-framework.org/documentation/bs3-customization#add-fonts
It should be the same in J4.
You can share the URL + super admin account of your site and tell me the font / where you added so I can check.
