EnumerateFiles Blocks UI thread even in Task.Run()
This is a functional example from my main project and all it does is basically show a green message for validation. It seems like such a headache but userfriendliness is my goal. ugh. Any alternative methods to achieve the same goal without blocking the UI thread?

Also, adding async to button_Click and await to LiveryValidate didn't change, still locks the UI while scanning.

Its odd, I think it looks right too, but it can't be like a .net bug can it?
