Tried the Windows build and I got this error. sadface
Hey! I did some research and this could boil down to a rouge anti-virus, or running an unsupported version (XP, Vista) of Windows. We're only supporting 7 and 10.

Running Windows 7 but antivirus.. hmm...
My mistake! This looks like a lower level Unity bug. I'll get a fix for this ASAP.
