Troubleshooting issue

I got the founders pack to play the smite 2 alpha and downloaded it through steam but every time I launch the game, I keep getting this message:

“Direct 12 is not supported on your system. Try running without the -dx 12 or -d3d 12 command line argument.”

I have no idea what this means or how to resolve the issue. I play on an HP and I have windows 10 and can play smite 1 with no problems. Anyone know how to fix this?
