I'm not sure if this is the correct place to be asking this, but I'm trying to add custom clothing to Unturned for a map I'm making. And I cannot open the Project or ExampleAssets unity package files. I've installed the recent version of unity but I've got the same results, and re-installed Unity Hub, etc.
To be more specific by saying cannot open, I click on either files in the sources folder and the loading wheel appears next to the cursor. But it doesn't load anything, unity doesn't open whatsoever.
