I was trying the most recent PC version of this game and about halfway through it stopped and the message that showed up in the Download list was 4426675-archive-default.xml and beneath it, it says couldn't download - no permission
Are you sure there is free space on the device for the download? It is 12 GBytes.
That message seems like coming from your PC, not a problem with the file server you download from. So examine your PC and the directory where the download goes.
You still have not revealed where you are downloading from. The Itch.io site or the mirror?
