When you selected 1.5 Preview 1, did you mean Preview 1. If you did, try updating to the release version of 1.5.
This report makes me think of microsoft/microsoft-ui-xaml#8806. This does look like it is fixed in 1.5.

I can't find the appropriate Windows App Runtime executable on MS's website

Yes, it seems like they fixed it in 1.5
