Yeah the .exe is there but linux dosn't use that, there should be an Unyielding2.86_64 file. Since there is none and the .dll files aren't also there the exe file tries loading them but dosn't find them resulting in wine crashing. It's just some linux specific things so if you didn't ever used it, i don't expect that you understend. Im just sayin that the uploaded linux version is badly created by unity, some setting inside it or (i don't know how this could happen) linux version mixed with the windows one.
TLDR
Windows executable is provided with linux specific libaries resulting with it being unusable
