Cycles Render Crash with GPU - AMD Radeon Pro 5500M

I did a fresh Windows 10 Pro install in Bootcamp on my 2019 MBP 16" and now Blender crashes/freezes every time I try a Cycles render with GPU. CPU rendering in cycles is OK. I have enabled CPU and GPU in preferences/system/OpenCL.

Before I did the fresh Windows 10 install I had no problem with GPU cycles rendering.

I have tried several other versions of blender. All with the same result. I have also uninstalled the graphics drivers and reinstalled to make sure it was the latest version. The card is recognized and works in other applications.

Any thoughts on why this is happening and how to fix?
