This is not a bug. Initializers of class members need to be evaluable at compile time so the compiler tries to interpret the body of function getTimeZone at compile time. Since lstat/GetFileAttributesW are not D functions that have available code, you end up with the (correct) error that is currently outputted. You can call those functions at runtime because you the object code is linked and you have no problems, but interpretation needs the source code.

Fortunately, there is a standard way of doing this, using a class static constructor [1] that were created for exactly this purpose:

import std.datetime.timezone;

class T {
    enum NEW_YORK_TIMEZONE = "America/New_York";
    public static const PosixTimeZone _timeZoneInfo;

    static this()
    {
        _timeZoneInfo = PosixTimeZone.getTimeZone(NEW_YORK_TIMEZONE);
    }
}

Closing this as invalid.

I am experiencing this issu and because I cannot use GDC, it is impossible to diagnose the source of "`lstat` cannot be interpreted at compile time [...]".

Please provide a call trace in the error message in DMD as does GDC.
