Ray-Tracing renderer not working, everything is black

Bug:

When RTX is enabled, the screen turns black except for particles:

Same place but with RTX OFF:

How to Reproduce:

1. Create a world with a third-party RTX Resources pack or import a world from the Marketplace such as Neon District or maps approved by Mojang and NVIDIA.
2. RTX will be working but every block of the game will be reflective because the resources supplied by the resources pack are not read by the RTX renderer. This happens because it is the first time you launch the game (first launch after an update / a fresh installation).
3. Disable RTX and re-enable RTX, Now the world will turn black except for all the particles.
4. Now the world will turn black except for all the particles.

What I tried to solve it:

1. I tried to re-install the game.
2. I checked if my NVIDIA driver was up to date (Watch Dogs Legion Optimised Driver) 

My configuration:

RTX 2060 (6GB VRAM)
Ryzen 5 2600 (6Cores / 12 Threads)
2x8 GB of RAM DDR4 3000MHz CL 15

System: Windows 10 Professional Version 2004 (19041.572)
