Describe the bug

I noticed that my app was crashing when trying to read the resources from a background thread:

var res = Application.Current?.Resources

I don't actually want to start using things, but rather I wanted to get the dispatcher queue and then enqueue a delegate to update the dictionary. But, it appears just reading this crashes the app and also adding Application.Current in the IDE's debug intermediate window also throws.

Steps to reproduce the bug

On a background thread:

var res = Application.Current?.Resources

Expected behavior

No crash and the resource dictionary is readable.
