After building Unreal Engine from source, the executable /Engine/Binaries/Linux/UnrealEditor can not be opened.
I have built the project in branch 5.2.1 release. I use RTX 3060 Mobile with Nvidia proprietory drivers. Packages xorg-x11-drv-nvidia, akmod-nvidia, vulkan, and vulkan-tools are all installed on system.
Here is the error log:
