Anyone else have issues with the Windows app?

It loads, but it doesn't show the contents of previous chats, it doesn't show the UI for settings even.

I've restarted the app and my laptop, and I've even uninstalled and reinstalled the app. Now when I try to login, the 'log in' button does nothing.

This was working last night, no software/driver installs since then. Mobile and web versions are fine.
