I've detected a bug related to this issue, and I'm currently working on a fix. In the meantime, you can try these steps to make it work

1. Open your Mac's terminal and run this command:

**rm -rf /Users/$USER/Library/Application\\ Support/atua**

(This will delete the application data.)

2. Remove Atua from the Applications folder.

3. Reinstall Atua and choose a different hotkey, like "command+shift+space.”

It should work after that
