Editor that was cross-built on Windows reportedly cannot start (using a Windows Subsystem for Linux or a VM).
On Windows cross build a Development Editor for Linux.
When its done building either check the Link-libUE4Editor-UnrealEd.so.link.bat file located on Windows at:
Engine/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development
Or copy this file from Windows to Linux and type ldd on it:
Engine/Binaries/Linux/libUE4Editor-UnrealEd.so
One with missing dependencies will look empty like:
bschaefer@bschaefer-Precision-T7600:WindowsBinaries$ ldd ./libUE4Editor-UnrealEd.so linux-vdso.so.1 => (0x00007ffc5a899000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f90673e2000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9067060000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f9066e58000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9066c54000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f906694b000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9066581000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f906636b000) /lib64/ld-linux-x86-64.so.2 (0x00007f906a977000)
A Valid one will look like:
