Kedro Viz stays waiting even if no valid project was found

Description

I accidentally launched Kedro Viz from the wrong directory and this is what I got:

kedro viz run

If you have created your project with Kedro version <0.17.0, make sure to update your project template. See https://github.com/kedro-org/kedro/blob/main/RELEASE.md#migration-guide-from-kedro-016-to-kedro-0170 for how to migrate your Kedro project.

...and it kept hanging there.

It would be nice if, in this case, it would immediately exit, since otherwise it gives the wrong impression that Kedro Viz is still serving something.

^C
Aborted!

(Cmd-C to cancel worked as expected)
