Font CSS stopped working

Site URL: http://www.amplifyher.nyc

This morning I woke up to find our entire website changed!  All of our custom fonts (NOKA black and Calibre Medium) entirely disappeared. Our branding that has been there for over 2 yrs went poof and the current version is really an eyesore!   I've been emailing and chatting with squarespace customer service throughout the day to discover there was some sort of platform upgrade that caused the CSS allowing for custom font to stop working.   The developer who set that up isn't reachable and I'm desperate to get our site back online.   Any thoughts/solutions?  This is a video showing where the code is, but I have no idea how to modify to get our fonts back online. https://share.squarespace.com/7KuLL02z   Happy to pay someone to help us out.  Thank you!

Did you get this fixed?
