My Minecraft installation was running perfectly - with RTX enabled - on my ASUS F15 laptop with an Nvidia RTX3060.

I CAN CONFIRM that the Minecraft 1.18.30 update is the culprit. After a system restore which got me back to Minecraft 1.18.12 everything was working perfectly normal again.

As soon as I updated Minecraft to 1.18.30 the program mostly crashes to desktop when attempting to load a RTX world.

However, sometimes the world will load and function. Upon saving it I may then get a CTD, but if not, and I then re-load the world I will get a black screen, with only toolbar and particle effects visible.
