Website is having problems with interactions and Nav Menu

UPDATE: I am adding and revising some info so people with similar problems can see it.

My website stopped working on March 2 after updating and publishing it. The problem causes the menu and interactions to not work. Also my website is supposed to have a video background on the homepage as well as a coupe interactions, but instead everything shows up as blank. This problem is also affecting the webflow.com homepage.
