I am confused

I got an admission from an engineering private school via Parcoursup, now I submitted my file to my Campus France space and I am waiting for their process to clear, meanwhile I created an account france-visas platform and in my portal I created a visa application, tho I am still waiting for Campus France validation... however it seemed like my visa application needs me to already provide a French address for where I am going to be, and when I started looking for student accommodation or whatever kind of accommodation, most of them require me to have a visa or "garant", like what ?? The visa application requires a "logement" address, and the "logement" requires me to have already a visa !! Can someone please help me with any kind of guidance!, Am I missing something here ?? How usually these processes go down ?
