Some Windows 10 UWP icons not displaying on search, or in settings

Some, but not all, icons for UWP apps are not displaying in search or settings. They do, however, display on the start menu when not searching. Icons for all non UWP apps display correctly, every time. UWP app icons are always present on the taskbar.

UPDATE: Many locally stored image thumbnails fail to appear in start menu search results either, no matter what image format.

The reason I have posted this as a separate question from this thread, is for the following differentiating reasons:

• Not all UWP app icons fail to display


• The issue is specifically present on the start menu only during search


• UWP apps never fail to display their icons on the taskbar

I have tried:

• Resetting the icon cache


• The solution here involving the windowsapps folder


• Creating a new user account


• Deleting iconstream registry keys


• 
  

  Changing performance settings to save thumbnails

  
  


• 
  

  Changing default app for PNGs

  
  


• Changing default app for all images in windows settings


• Changing windows explorer view settings


• Updating graphics drivers
