Local OS (where xxh is installed): Arch Linux
Destination host OS: Proxmox VE8
xxh version: 0.8.14
xxh-plugins installed: xxh-plugin-prerun-core, xxh-shell-xonsh, & a custom plugin for my alias scripts

Steps to Reproduce
simply run xxh installed in python 3.13. I used pipx in this case, the command used was xxh <IP>

running it in 3.13 trows re.PatternError: nothing to repeat at position 0. As I understand it, the re module is stricter in 3.13 and will throw an error when empty or malformed.

xxh config included.
