Missing library-name in .lib statement. Could you try with library-name, for example "typical"? If nothing specified in .lib statement, .lib read nothing from sm141064.ngspice. So, the subckt nfet_03v3 is undefined.
If compatibility option is set, .lib can be used as .include. But basically, .lib needs library-name after filename. https://ngspice.sourceforge.io/docs/ngspice-html-manual/manual.xhtml#sec__LIB
