I had the same issue and resolved it the same way as Tom Blackburn. Once I manually downloaded the NVidia driver update, Minecraft raytracing started working properly and the game looks absolutely gorgeous.
It's fixed! I had to manually find and download the appropriate NVidia driver update, but once I did that the raytracing features started working correctly, exactly as reported by Tom Blackburn in the duplicate issue report.
