im not a fan of win 10, so i stuck with 7 for the time being, i dont plan on "upgrading" until i build my next machine, which i was gonna do, but the rona hit, so holding off any superfluous waste in case of emergency.Let me gues... you don't use the latest Version of Win 10?
Unity Updated it's videoplayer engine which broke compatibility with older OS apparently.
Have seen this in plenty of the latest Unity games... however several Devs fixed this by converting to a different Videoformat.
Not sure how CrazyForgeStudio intends to fix this... if at all
