try downloading from another site because the current version is 0.8.5 there is no such thing as 0.8.6 maybe the one you have is a fake build because there are some sites that gives fake version's of the game those are scam so be careful here are some of the sites that I download from they're safe so you can try them: F95ZONE,DIKGAMES, PLATINMODS,VisitMama
Some of this are the one I trust and they're always up-to-date with itch.io hope I was of help 😊
