**Additional context**

That is on a 64GB M1 max laptop, so bit unexpected. I wonder if that is caused by node running out of memory as I encountered recently another issue with it that required me to add `NODE_OPTIONS=--max-old-space-size=4096` in order to just run `yarn webpack`... :p

Commencez par l’échec de textDocument/completion et l’erreur de chargement YAML signalée dans la stack trace de dist/extension-node.js. Reproduisez le problème avec un workflow réel, puisque les étapes de reproduction du rapport sont des espaces réservés, puis suivez la requête de completion jusqu’à identifier l’augmentation de la pile d’appels ou de la mémoire. Le travail est terminé lorsque completion ne dépasse plus la pile d’appels et que les fichiers YAML sont chargés avec succès.
