Describe the Bug

I just spent 6 hours trying to track down why I couldn't astro build or astro dev without indefinite hanging.

astro dev would just load indefinitely with no response and no feedback from command line.

Turns out I accidentally added a backward slash to the end of the layout property:

layout: ../../layouts/MainLayout.astro\

This stuck me so bad I hope publishing this at least helps someone else who's stuck

Here's demo using the Minimal Reproducible Example attached:

Sorry you ran into this one @ThatGuySam, that definitely sounds frustrating! Looks like we have a good opportunity here for better DX validating the layout frontmatter and providing a useful error message 👍

Marking this as nice to have mainly because it's a DX improvement and not necessarily a bug fix, but DX is high on our list of goals before a 1.0 release so I'm hoping we'll be able to take care of this soon!

@tony-sull Yeah at the very least this issue and my solution will show up when searching for astro silent hanging and they don't have to waste hours of their life on a single typo
