I found a fix. I copied the root folder from anotherunity game across and then unpcked the game again overwritting all the files and I got the menu. It looks like there are a couple of files missing.
In my yokai root folder I now have uninst000.dat, uninsta000.exe, UnityCrashHandler64.exe, UnityPlayer.dll, WinPixEventRuntime.dll and Yokai.exe
I'll test the game and post a video.
Thanks
