What's Wrong?

Claude.exe was installed and working great on my machine. Yesterday I started to experience this issue which persists even after uninstall/install.

If I launch Claude in powershell the welcome message shows up, I can control the keyboard for like 1-2 seconds, then it freezes and exits.

Where can I find logs to debug this further?

(I tried to run claude in cmd terminal and it doesn't display anything and just quits after a while.)

What Should Happen?

Claude.exe should not freeze.
