Question

On Drupal 8, I have a style and a empty module :

When my module is installed and the cache clear, my custom theme is broken:

Why my custom and empty module break my custom theme please ? Without the addon all is OK:

Answer 1

Is your custom theme called nature?

That's not allowed, you can't have modules and themes with the same name.
