Regex is considered as not working when it should

[zhinu]

Describe the bug
While adding a the following regex
([^A-Za-zÀ-ÖØ-öø-ž]+(table)s?[^A-Za-zÀ-ÖØ-öø-ž]+(pique)[^A-Za-zÀ-ÖØ-öø-ž]*(nique)[^A-Za-zÀ-ÖØ-öø-ž]*)
for the link https://www.cemonjardin.com/l/produits/mobilier-de-jardin/tables-de-pique-nique.html
I get an error message

Expected behavior
This regex was designed to avoid false positives (for instance matching épique volcanique when wanting to match pique-nique)
