Demo app doesn't run "No directory provided for file keyring"

[broady]

Ran into this error from another CLI I'm trying to use.

Tried to run the demo app. I get the following error. I don't know which backend it came from, or how to provide a directory for "file keyring".

I'm on WSL2. Distro info attached.
