Sometimes when I'm offline, I'll start up the Minecraft launcher and click play. It'll say that game files are missing and need to be downloaded online. I go into my Minecraft folder/assets/indexes, and the version of Minecraft index json got deleted! I usually just keep backups of my index jsons now in case of them being deleted

Have you tried resetting your PC after each deletion of the .minecraft folder?
Do you have enough free space on your disc drive?
Do you have an antivirus on your PC that might cause launching problem?
