What's Wrong?

I’m on Windows 11 Pro 25H2 (64 bit) and Claude Desktop version 1.2773.0.0. When I launch the app, it starts as a background process in Task Manager but no window ever appears. I’ve already uninstalled and reinstalled the latest version, with no change.

What Should Happen?

Claude Desktop should launch and display the main application window when I double-click the executable or launch it from the Start menu.
