Cannot use polyglossia/babel with biblatex in LuaTeX: etoolbox Toggle undefined

This is an example test.tex document. Both babel and polyglossia failed and produce the same error:

documentclass{book}

%usepackage[vietnamese]{babel}
usepackage{polyglossia}
setdefaultlanguage{vietnamese}

usepackage{biblatex}


title{Sth}

begin{document}

maketitle

end{document}

This is the full log. And my config for VS Code:

"latex-workshop.latex.recipes": [
    {
        "name": "lualatex->biber",
        "tools": [
            "lualatex",
            // "biber",
        ]
    }
],
"latex-workshop.latex.tools": [
    {
        "name": "lualatex",
        "command": "lualatex",
        "args": [
            "--shell-escape",
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "-pdf",
            "%DOC%"
        ]
    },
    {
        "name": "biber",
        "command": "biber",
        "args": [
            "%DOCFILE%"
        ]
    }
],

I installed all Vietnamese-related package I found using tlmgr search, notably babel-vietnamese and vntex, to no avail.

When I use English language, it works. When I paste the exact document to Overleaf, it also works. So it’s something on my part. How can I fix this?
