Install a custom empty module break my custom style On Drupal 8, I have a style and a empty module :

/modules/kyna/nature/

/modules/kyna/nature/nature.info.yml

name: 'Nature Theme Structure and configuration'
type: module
description: 'Example Module description'
package: Kyna
version: VERSION
core: 8.x


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:


Thanks.
Is your custom theme called nature?

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