Application icon appears blank/generic if the loaded event is processing background task

**Setup for WPF App:**

**Set Project settings icon location:**

**After running the wpf app, the icon on the taskbar is blank.**

**Note this does not occur on Windows 10**

Here is a link to an article describing a similar issue after the latest update: https://learn.microsoft.com/en-us/answers/questions/2201775/windows-forms-application-icon-suddenly-shows-as-d

We're trying to fix an issue where the icon randomly disappears though the behaviour is difficult to replicate seeing as this only happens ever so often.
