Hi, I get a bug when I trying to compile a program in UE4.27 with Nvidia TITAN RTX. The drivers is 535.171.04 . And it is in Ubuntu 20.04. I have following error in the terminal:

I think the main error is " Ensure condition failed: VendorId != EGpuVendorId::Unknown" that UE4 can’t find my Nvidia TITAN RTX. But I can’t find a way to solve the bug. There is some same question on internet but none of them find a solution.
