Did you mean this line:

File:./Runtime/Core/Private/HAL/ConsoleManager.cpp] [Line: 556]

I have same issue on clean new project with full build from source on Windows as well. (VS 2022)

Did you remove/comment that line you marked?

As @KetherGame said, I erased that line in the code and recomiled the engine(branch 5.0). It works!

  • Ubuntu 20.04
  • Nvidia RTX 2080 Super Max-Q (Nvidia Driver : 495.44)
  • Vulkan Instance Version : 1.2.131

Good, i’ll try it.

My specs:

  • Zorin OS 16
  • GeForce GTX 1050 Ti
  • 32 GB RAM
  • AMD® Ryzen 5 3600 6-core processor

Thanks! It works on me too.
