/media/pi/PortableHD/terrariaserver/tmodloader-1.3.5.3-v.0.11.6.2$ mono tModLoaderServer.execant resolve internal call to "System.ComponentModel.Win32Exception::W32ErrorMessage" (tested without signature also)

Your mono runtime and class libraries are out of sync.
The out of sync library is: /media/pi/PortableHD/terrariaserver/tmodloader-1.3.5.3-v.0.11.6.2/System.dll
When you update one from git you need to update, compile and install
the other too.
Do not report this as a bug unless you're sure you have updated correctly:
you probably have a broken mono install.
If you see other errors or faults after this message they are probably related
and you need to fix your mono install first.
