Select Wii U USB adapter crashes Dolphin

[Toadofsky]

I've been able to use the GC USB adapter for dolphin 5.0 for some time. In the past weeks, I was trying to setup the GC controller as a xbox type controller via the GC USB program and using vJoy. But then going and trying to select the GC USB adapter under controller options causes Dolphin to crash. I cannot figure out why this is happening. I have used Zadig to try and fix the problem, and I've had zero success, Dolphin just keeps crashing when I select the GC USB adapter. What am I doing wrong and is there any way to fix this? I have tried uninstalling Dolphin and reinstalling but that still isn't helping.
