Error: Unable to create Monero wallet (Cannot create wallet. Already exists.)
**Describe the bug**

First, there's no easy way to rerun the interactive configuration. I deleted the config file to trigger it.
Therefore, I'm not sure if this error is because I ran `asb start` a second time or because I deleted the config file.
Someone else can figure out the race condition.
