The notifications permission has nothing to do with my suggestion, though: it only affects the ability of the site to post toast-style notifications to your browser and/or operating system.
What you’re dealing with sounds more like the site is not getting rendered correctly, but I’m at loss why this would happen only in Chrome and not other browsers.
If this is happening on your home/personal network, are you running some filtering proxy?
If the answer is no, the only other thing that comes to mind, presently, would be to uninstall and reinstall Chrome. Not great, but unless someone comes along with a bright idea, I feel like we’re running out of options.
BTW there is no screenshot attached to your last post.
