Minecraft launcher stuck on preparing.

Hi to whoever reads this. I have been trying for days and hours each time to get my minecraft launcher to work. It opens up but once I press play my launcher quickly loads up to a little bit over half, and stays stuck there. I dont use any mods, no apps are running, and I have already tried updating my launcher. All I want to do is play minecraft java with my friends. Is there something else I can do to get my launcher to work? I already uninstalled and reinstalled twice.
