Why did Copilot suddenly get depressed??

I've been an avid user of copilot for a while now because of Uni and specifically bought the Samsung Book 6 laptop for the ingrained copilot. Well, today I opened the app and everything was completely grey. It didn't even greet me. I have a slight visual impairment and now I can't tell the different buttons apart from the flat grey background. Who thought this was a good idea, nevermind one that would bring revenue?!! I'm just mad that I'll lose all my conversations because the app is no longer accessible.
