Valorant not deleting/opening/updating

I wanted to play valorant but sometimes its just a black screen, when I restart my pc it said I need to update it and I tried I got an error, then after that it said I need space, I decided to uninstall it so I can redownload it to my other Disk but I couldnt even delete Valorant or Riot Client from my settings I dont understand what to do, even when I download a new riot client and valorant game I cant it tells me not enough disk space when I clearly picked Disk D.
