Invariably, "works from the shell, fails in SCons" means you're depending on something in PATH, or some environment variable. SCons by default ignores the PATH from the external environment, and environment variable settings.

This is a FAQ question even...
https://scons.org/faq.html#Why_doesn.27t_SCons_find_my_compiler.2BAC8-linker.2BAC8-etc..3F_I_can_execute_it_just_fine_from_the_command_line.

I don't know anything about zig, but based on error: AppDataDirUnavailable, I'd guess SCons is finding the zig binary, but some other shell environment variables the zig compiler needs aren't being set in SCons or propagated from your shell to SCons.

Likely you need something like

env['ENV']['SOME_ZIP_SHELL_VARIABLE'] = os.environ('SOME_ZIP_SHELL_VARIABLE')
