How do I fix a "permission denied" error in Launch?

If you encounter the error message Launch Error: Permission denied, it indicates insufficient permissions to log to the desired project. Possible causes include:

1. You are not logged in on this machine. Run wandb login in the command line.
2. The specified entity does not exist. The entity must be your username or an existing team's name. Create a team if necessary with the Subscriptions page.
3. You lack project permissions. Request the project creator to change the privacy setting to Open to allow logging runs to the project.
