Hi,

I faced exactly the same issue this week after I re-installed BIAB 2018 on my re-imaged Windows 10 Laptop.
I all the ideas in this thread and a lot of other stuff, but it did not work. Then some research gave me a hint that another malfunctioning DX component on my PC may be causing the hang of BIAB.

So I unplugged all USB devices from my Laptop and tried, and it worked fine.

By trial and error, I located it to faulty driver for M-Audio M-track. I repaired the driver using Windows, and after that the problem is gone.

I am posting it to this thread as it may help someone else who may be stuck like me. Please look for problem in the drivers for your add-on devices if you face a hang while scanning DX plugins.

Warm Regards,

Sanjay Jain
