Drew Dunk's solution (at the bottom) solved this problem for me.

In Windows 11, the XPS Document Writer AND Viewer are hidden and don't always show up when you click on add optional features. I posted the XPS writer info above and may not have been clear enough when I said "Do the same thing for the XPS Document Viewer." Here's the instructions on installing the XPS viewer:

1. Window+R

2. Type “optionalfeatures”

3. Find Microsoft XPS Document Viewer 

4. Check Microsoft XPS Document Viewer

5. Hit OK, let Windows run
