Code 12 with Core X and AMD 5700 xt

Hi. have a early 2019 Razer Blade Stealth and I just got a Core X and a Saphire Nitro+ Radeon RX 5700 XT card. No matter what I try the AMD Radeon driver install returns an error 207 upon install, all versions, and the card is listed with a Code 12 in device manager. I've updated the bios, firmware, and ME on the laptop. Tried with both Windows 10 versions 1909 and 2004, same results. Any ideas? Or should I return this card and get something else. What is a card that will just work with this setup? Thanks for your help.
