Can't start local dev deployment

🪲Bug Report
I have been able to run local dev deployments previously, but today it asked me to authenticate again and once I did, my local dev deployment for this project stopped working. I've tried clearing the local backend folder, changing the device name, re-configuring, etc. Nothing has worked. I also tried to delete the deployment in the Convex dashboard, but it's not running and won't let me manage it.

This is the error I get via the CLI:

Error fetching POST https://api.convex.dev/api/local_deployment/start 400 Bad Request: LocalDeploymentMismatch: The deployment local-jling-u_do-1 does not match the provided device name, or project.

How can I resolve this?
