### Describe the Bug

* Log out of wrangler.
* Run `wrangler dev -c -c ` where at least one of the configs has a Workers AI binding.
* Wrangler will pop open a browser window to log in. Close it.
* Now the wrangler session has errored, but it's still running in the terminal, and ctrl+C won't close it.
* You have to kill the process from another terminal window.
