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

If you see the error Launch Error: Permission denied, you don’t have permission to log to the project. Review the following causes and resolutions:

You aren’t logged in on this machine. Run wandb login in the command line.
The specified entity doesn’t exist. The entity must be your username or the name of an existing team. If necessary, create a team on the Subscriptions page.
You lack project permissions. Ask the project creator to change the privacy setting to Open so you can log runs to the project.
