‘Driver PNP Watchdog’ error trying to install windows 10 on 2020 iMac

2020 iMac with 4TB SSD, Radeon 5700. Catalina up to date.


Tried installing Windows 10 (both 20H2 build and 1909 build) without success. Boot camp partitions just fine and iMac reboots to windows blank blue screen ‘setup is starting’ then crashes to BSOD with Stop error = Driver_PNP_WatchDog. I then have to reclaim the boot camp partition in disk utility. AppleCare could not find solution as this is on the Windows side. I have not pinged Microsoft hard yet but a quick internet search shows this error as a problem on Windows machines tied to many types of issues from device drivers to BIOS drive controller. Any ideas?
