How to kill a build?

I am building a snap locally. The last attempt has been running for over an hour and I am sure that it is stuck in a loop or something. How do I kill the process? I ask because I have in the past simply Ctrl+C to stop it but I would then need to uninstall and reinstall multipass to be able to do anything with snapcraft. Is there a safe way to stop the build?

Can you use ctrl+c to interrupt the build, then snapcraft clean?

Thanks for the suggestion. After the Ctrl+C I am not able to do anything with snapcraft as it almost immediately complains the there is something wrong with multipass. I can’t remember the error message. It is working fine now so I may need to update this post again later when I can get the error message.
