LaTeX minted package not working with `\begin{minted}` anymore on win10?

Question

I've been using minted without any problem for years. I'm an Windows 10 and MacOS.

Here's a minimal example compiled with xelatex:

\documentclass{article}
\usepackage{unicode-math}
\usepackage{minted}

Hi !

\begin{document}
\begin{minted}{python}
print("hello")
\end{minted}

\end{document}

This produces only "Hi !" and does not print the python code anymore without returning any error message, whereas \mintinline and \inputmint work just fine.

I reinstalled Win10 several times, trying on MikTeX and TeXLive, compiling with TeXstudio or TeXworks to no avail (of course using -shell-escape).

I tried several versions of pygments. I use Python 3.9.9.

Everything works fine on my mac, though.

Does anyone have a clue ?

Thanks in advance.
