Update:
Ge-force experience did not allow me to update to the newest driver. I got the newest driver from online and it worked great!
I am experiencing the same issue
Build: intel core i7 (hexa core), 16gb RAM, rtx 2060.
Currently all of the sample rtx maps are pitch black with ray tracing enabled
It needs to have support for ray tracing. Hence the minecraft with "RTX"
