Missing / white textures

Since the latest update the missing textures problem from last year is back on my PC. Particularly when there’s fog, nearly all intermediate textures are white. Additionally, there are missing or white textures on the Col de Zwift climbs at the edge of the road.

I am having this same issue with the roads up Alpes. All of them are white and the headlamp lighting effect is obviously broken.
