@mini-i5, The 2020 13-in Ice Lake MacBook Pro is different than the rest of Thunderbolt 3 Macs. It's currently the only Intel Mac with integrated Thunderbolt controllers so the Boot Camp setup procedure for AMD cards is much different. I have tested Win10 20H2 on my 2020 13-in Ice Lake MBP and it doesn't work. I have to use Win10 1903 V1 with three out of four TB3 ports disabled in Device Manager.

@bradley-beal, I used the same guide and it works fine. I even have both the internal and external screens work properly. Note that I am using a 5700xt. If I remember well it didn't work the first time so it tried a couple of times before it worked. One you find a guide with exactly the hardware you have just try a couple of times. Also read similar guides ie same laptop different card or same card different Mac as this could help you figure out the small tricks you can do to get over some some of the minor issues.

@tsakal, Ive tried just about every resource on here at this point. This guide got me the closest to success so far. Still cant get around error 43. Ive tried this one fully, twice. Tried 4 different drivers, have 3 thunderbolt ports disabled, camera, and igpu disabled. Tried registry hacks and a boot loader. Im thinking the chroma is taking too many resources but I shut off the RGB and disabled the usb ports on the back of it as well. 

I am however, a patient man, and don't like to waste money -  so I will get this damned this working. Can't believe how simple it is in MAC OS vs all this jumping through hoops.

@bradley-beal, I can't be of much help since I have neither the eGPU nor the 2020 MBP anymore.  I've jumped into the M1 Pool.  I do however recall that I ran into a similar issue as you, and resetting the SMC and/or PRAM and VRAM got me out of the error 43.

@bradley-beal, good luck. The chroma could be the issue in your case.  in my case I had not problem with windows 1903 and for the windows 2004 I had to do the pci.sys swap which worked fine. The whole situation is very random that is why you need to start with a guide with exactly the same hardware and then read a couple more which have parts of your setup and try one by one. 

ps put your system details in your profile it helps to know what you are working with.
