When I start UE4Editor on linux I get this symbol lookup error:

[Me@nixos:~]$ UE4Editor
./UE4Editor: symbol lookup error: /home/Me/.config/unreal-engine-nix-workdir/Engine/Binaries/Linux/libUE4Editor-UnrealEd.so: undefined symbol: _ZN20UTrueTypeFontFactory12LoadFontFaceEPviP16FFeedbackContextPS0_

[Me@nixos:~]$ echo _ZN20UTrueTypeFontFactory12LoadFontFaceEPviP16FFeedbackContextPS0_ | c++filt 
UTrueTypeFontFactory::LoadFontFace(void*, int, FFeedbackContext*, void**)

What is the cause of this error nad how do I fix it ?
