I have a problem formatting my subsubsection title using titlesec. From my code, I would have thought the Subsubsection title was numbered I.1.1 but I don't see any number on my resulting file:

result

I noticed that by passing \documentclass{article}, the problem did not occur

Do you have any idea where the problem could come from?

My code:

\RequirePackage{fix-cm}
\documentclass{book}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc} 
\usepackage[french]{babel}
\usepackage[left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}


\usepackage{array}
\usepackage{enumitem}  %pour l'option [resume] qui permet de reprendre la numérotation
\usepackage{pifont}
%\usepackage{tabularx}
%\usepackage{tabulary}
\usepackage{tabularray}
\UseTblrLibrary{amsmath,booktabs,counter,diagbox,siunitx,varwidth}
\usepackage[export]{adjustbox}
%\usepackage{verbatim}
\usepackage{multicol}
\usepackage{appendix}
\usepackage{libertine}
\usepackage{graphicx}
%\usepackage{picinpar}


\usepackage[european, RPvoltages, straightvoltages]{circuitikz}
\usepackage{siunitx}
\usepackage{hyperref}

\usepackage[Rejne]{fncychap}


\usepackage{pgf-spectra}


\newcolumntype{Y}{>{\centering\arraybackslash}X}

\titlespacing{\section}{0pt}{6}{0.5}

If you want the numbers of \subsection-level headers -- and, presumably, of \section-level headers as well -- to include the chapter number, you need to change

\titleformat{\section}[hang]{\LARGE \bfseries}{\Roman{section}.}{1em}{}
\titleformat{\subsection}[hang]{\Large \bfseries}{\Roman{section}.\arabic{subsection}}{1em}{}

to

\titleformat{\section}[hang]{\LARGE\bfseries}{\arabic{chapter}.\Roman{section}.}{1em}{}
\titleformat{\subsection}[hang]{\Large\bfseries}{\arabic{chapter}.\Roman{section}.\arabic{subsection}}{1em}{}

If you want subsubsection-level headers to be numbered, you further need to run

\setcounter{secnumdepth}{3}

as the default value of the secnumdepth counter is 2 in the book document class.
