I am missing an alias for a derived table - mysql

Question

I know, this question has been asked very often but I know my error, I know how I could fix it, but I can´t find the point where the error is. In my opinion, all the subqueries have different and unique names, I even gave the columns different names then the subqueries. Any help would be appreciated. Where is the point I am missing an alias?
Whenever I am trying to run this query I get the response "Every derived table must have its alias", which is an understandable error message, but I can't figure out where my error is located.
