Ray-Tracing renderer not working in 1.16.30.57 / Not allowed to enable DLSS or Upscaling method

EDIT : By re-installing the game, everything doesn't work as intented --> same thing is happening : the black screen while rtx is on.

Just updated Minecraft Windows 10 in the RTX beta to the version 1.16.30.57 on the Microsoft Store. The previous version 1.16.20.x worked perfectly.

STEP TO REPRODUCE :

1. Update miencraft to the latest version

2. Launch minecraft

3. Play on any world approved by NVIDIA or play on you maps with custom RTX resources pack (like this one : https://mazewave.github.io/index.html )

4. See that's you have a Black screen (First screen below)

EXTRA STEPS :

1. If you have to install the game for the first time, RTX will be enabled and functionning but any "_mer" textures will not be applied and the world looks like platic.

2. Reboot the game

3. Play on any world approved by NVIDIA or play on you maps with custom RTX resources pack (like this one : https://mazewave.github.io/index.html )

When RTX is ON, im just getting a black screen : In the one hand, the NIVIDIA RTX renderer seem to be broken or corrupted but on the other hand, the game still run perfectly and won't crash at any time.

But when RTX is OFF, i can see the world :

Im not allowed to activate Upscaling in the settings :

But again a weird bug happening, the only chunks distance I can select while RTX is off, is 5 chunks minimum and maximum :

Better information about my PC Setup :
Windows 10 : Up to date
