Plutonium

When downloading my game, the correct files are not being downloaded. I have had this game on my computer before and it's ran fine (it was the old old download with the new launcher) and I recently reset my PC for another reason so had to reinstall, however this time it will not work. I'm not sure if it is my PC deleting the files or not.
I don't have any active antivirus on my computer so I doubt anything would be causing them to delete. In the image above these are the only files that are being downloaded at installation, and when I tried to use the launcher to play it crashes and deletes itself instantly. Any help would be appreciated thankyou
