I would translate it like this: "All these elements have obscured and excluded the other factors and key players that have led to an exacerbation of the problem of sexual violence in armed conflict". We don't have a verb "to invisibilise" in standard English (though it sounds good!). You can "make sth invisible" but this feels too literal for your context. If you wanted a stronger verb, you could use "ignore" or "eclipse". [Edited after reading your comment] I'm not an advanced Spanish speaker so treat my comments with caution. It was an interesting challenge.

It depends on what you mean with "sujetos". And the main problem is that the spanish version is not correct. The word invisibilizar doesn't exist in Spanish. It would be: ocultado. The expressión "conllevado a" is not correct. It would be: conllevado el exacerbamiento del problema..." And the other question is: ¿qué ha provocado el exacerbamiento o exacerbación del problema de la violencia, lo que tu llamas estos elementos o los sujetos y aspectos? Depending on this, your traslation could be right or not.
