My Copilot is not working at all. Just blank

When I pull up the Copilot app on my desktop, it is just blank. When I try to access it on the website, it just thinks and thinks and thinks. I have Microsoft 365 Personal which has always included Copilot, but now it is not working. I have restarted my computer, I have downloaded the app and installed it again. I keep asking the Get Help app, but it also just thinks for ever.
