Errors of UE4 in linux

im learning UE4 on linux i tried to create a new project but the editor blocked in 96% loading and the terminal show me this error : LogMaterial: Missing cached shader map for material M_Metal_Copper, compiling.
pls how to fixe it

Make sure you have the latest greatest drivers for your gpu. Try opening the folder ue4. go to unreal engine/release/binaries/linux and scroll down to the UE4editor. Try creating a starter project with starter content. If that doesnt work properly you may have to attempt a re install.

thank you
it worked
