Loading a world with RTX/ray tracing disabled and then enabling it causes skin to turn black

This is an extension of MCPE-156577.

This problem happens after I loaded an RTX pack but turned off ray tracing. When you enter the world and turn ray tracing on, you can see the black skin.

MCPE-156577 has been fixed, but it seems that the problem is not fixed completely.

Steps to Reproduce:

1. Activate an RTX pack in Settings > Global Resources
2. Navigate to Settings > Video and make sure that the Ray Tracing option is disabled
3. Open a world and enable RTX
4. Look at the player's skin

Observed Results:
The player's skin is completely black.

Expected Results:
The player's skin should look the same as it does when RTX is disabled.
