It's weird, I checked and I have DX12, but I read that a similar error can even be trivial because I have a laptop, but no big deal, I'll watch the game on YouTube :D
That's frustrating! Some laptops have both integrated and dedicated GPUs, and sometimes the game might be trying to use the integrated GPU which may not support DX12 properly. You could try forcing the game to use your dedicated GPU through your graphics card control panel (NVIDIA Control Panel or AMD Radeon Settings). Also worth checking if your GPU drivers are fully up to date. Hope you can get it working!
