I can't load the Colour, Light and Shadow RTX world.

 
All of the other RTX and non-RTX worlds load fine, but when I click on 'Create this world!' in the marketplace it says Generating world, and after about 10 seconds Minecraft crashes and returns to the desktop. Even with the world in the lists of 'My worlds' I am still unable to launch it. The world size when downloaded is about 0.42MB, if that helps.
