What's Wrong?

Desktop app version: 1.6259.1.0
Windows version
MSIX installation from Microsoft Store
Blank white screen on every launch
Nothing reported in Windows > Logs >Application
I open the desktop app and only get a blank screen with the minimize, maximize, and close buttons at the top.
When ts with Claude and Fin it says "The MSIX installation path is unusual - most users install via the standard installer rather than through the Microsoft Store, which might be contributing to the issue." But then I point it to https://claude.com/download and it says that is the official download method.

What Should Happen?

The screen should populate with options and previous chats on the left an allow input on the right
