Failing to navigate to page with the Grid

[Osmosis311]

Using an XF app with Prism, trying to navigate to a page that has the Grid control, it won't even complete the navigation. Some error must be happening behind the scenes that it doesn't show me.

In the XAML editor, I am seeing this error, if it's relevant:

Thanks!

It is a very generic issue, probably not caused from navigation, but initialization. I'll need more detail or sample code to make comment.
