Keyboard shortcut to stop an Automator service (Quick Action)

Try the following:

Create a new Automator Quick Action.
- Workflow receives [no input] in [Mail]
Add a Run Shell Script action.
- Shell: [/bin/zsh]
- Pass input: [to stdin]
Add the following command to the Run Shell Script action:
- pkill -9 com.apple.automator.runner

Notes:

In System Preferences > Keyboard > Shortcuts > Services I assigned it a keyboard shortcut of: ⌃⌥⌘Q

I tested this in macOS Catalina, as I do not have Mail setup under macOS Big Sur, and it work for me without issue.

This will kill all Automator Service/Quick Action that are running.
