Missing Files For Unity Tutorial Project Stealth Any Help?

Downloaded the stealth tutorial set, yes i’m rather new, yet half the folders and files are missing since the last time I’ve gone through it. Was the new update something to do with it or have I done something wrong? Any help is appreciated as i’m just a beginner and am having a hard time with it.

I was having a very similar issue - either Unity will crash, or some folders won’t make it over. It looks like there is a broken file in the latest package. I found the solution on the comments section in the Unity Store: When importing, deselect the GraphicsSettings.asset file, and the rest of the folders (Materials, Models, etc) will import okay. I do not know if anything is lost from the exclusion of that file; it plays perfectly fine.
