Duplicating the generation of index.html with nested paths
[issue link]Hello!
Found a strange behavior when generating static.
index.html is generated twice and it seems the second time the correct one is re-written
(It seems that because of this I can not open the page by a direct link - get [nuxt] Error while initializing app DOMException: Failed to execute ‘appendChild’ on ‘Node’: This node type does not support this method.).
Is this a bug or not?
A similar issue was created earlier

Below I attach a screenshot with the structure / pages, the paths of the router and logs
