[Windows] Gmod 13 server.dll error on SRCDS run

Surprisingly the title fits the issue =)

“ConVarRef mat_dxlevel doesn’t point to an existing ConVar”
“Could not get IServerGameDLL interface from library server.dll”

was the error that I got running the server.bat file for cmd prompt
with the actual SRCDS.exe, it pulls up the box; click “start server” and it just disappears nothing happens
