Failed to load native core functions! Couldnt find at location! (Ubuntu 20.04 + Debian 11)

Unhandled Exception:
System.IO.FileNotFoundException: Failed to load native core functions! Couldnt find at location /home/foo/Desktop/ReClass.NET-master/build/Debug/x64/NativeCore.so

I have #241 on both x64 and x86 builds on Ubuntu 22.04 and Debian 11

Built with docker and msbuild, error identical.
