I’ve definitely come across this genre of issue on many sites in the past when checking out the console when a site is broken. Page is just a blank white screen? Oh, looks like the render function was placed after the init for some 3rd party user monitoring, which crashed because the script didn’t load properly. “Complete Checkout” button just does nothing at all? Oh, looks like the code to take my money runs in a callback to some analytics script that my ad blocker blocked. Oops.
