I can't index my pages. Google bots don't explore my pages

[Ms. Alessia]

Hi guys,
I've created a website in April. Google explored it beginning of April, but didn't index my pages. Site was still in the building, but now, I've completed it and I'd like to index my pages. Nevertheless, when I request "page indexation", Google doesn't do it. It visibly doesn't even explore again my pages. I have 2 "class" of pages considered by Google: "Explored, currently not indexed" (Pages Google already explored in april) or "Detected, currently not indexed" (Pages newly created since April).
What I've done: I've well recorded my sitemap + I've blocked the indexation of pages showing "?search=" or "?s=" in the content.
The validation status is written as "started", but no exploration, nor nothing has been done since 2nd of September (When I wanted to index again my pages).

Do you know if I made something wrong? Or what should I do to correct it?

Thanks in advance for your precious help !
