I tried many different version of Proton and even try to install mdx or dxd12 using ProtonTricks and winecfg inside, but I just can't start the game, it says in a dialog :

Failed to initialize Direct3D 12. Check that your graphics hardware meets minimum requirements and that you have the latest drivers installed.

With in the background a white window from the game called Miencraft Legends and then crash when clicking on OK

Games dosen't open.
