This happens for me as well. I'm using win7 still, and the issue is the Node.js version used in Aki.Server.exe is higher than is supported for win7.
From cmd window:
e:\Program Files\Battlestate Games\Tarkov SP>Aki.Server.exe
Node.js is only supported on Windows 8.1, Windows Server 2012 R2, or higher.
Setting the NODE_SKIP_PLATFORM_CHECK environment variable to 1 skips this
check, but Node.js might not execute correctly. Any issues encountered on
unsupported platforms will not be fixed.
Would be helpful to add a note about using Windows 7 for this mod.
