BootCamp support software installer causes bluescreen at "Apple USB Virtual Host Controller"

Hi,

I've recently been trying to get BootCamp to work on a external SSD following this: https://9to5mac.com/2020/07/14/install-windows-mac-external-ssd-drive-boot-camp-2020-video/

However, when i get to the very last step, which is manually installing the BootCamp drivers, Windows will bluescreen at "Apple USB Virtual Host Controller" with the following stopcode: "DRIVER_VERIFIER_DMA_VIOLATION". The BSOD will be stuck at 0% unless i force power-off the machine.

My question is:

How do i fix this?

MacBook Air 13″, macOS 10.15

Installing Windows on an external disk is not officially supported. If you really must have it on an external disk,

either install Windows on the internal disk first, and then clone it, or,
use Win2USB.

The BSoD is because your external disk is connected using the controller and driver that you are trying to install. Under normal circumstances, with the internal disk, the connection to the boot disk is not a USB.
