There was a problem loading pack Texturpaket Natur.

After the last update, the Nature texture pack no longer works.
Version 1.0.64
Nintendo Switch system version: 18.0.1
When loading a Minecraft (version V1.20.80) world, an error message appears:
Error! There was a problem loading pack Texturpaket Natur. 

We uninstalled the Nature texture pack, then reset the cache and keyboard.
Then restarted the switch and reinstalled and activated the Nature texture package.
Afterwards, 1 world could be loaded and played. However, when switching to another world, the same error message appeared again.
"There was a problem loading pack Texturpaket Natur."

Now we cannot play a world with the Natural texture pack.
