Bonsoir à vous tous
Je demande votre aide pour résoudre un problème.
J'ai un projet (que je n'ai pas encore fini) que je n'arrive plus à modifier. Car quand je modifie même une lettre dans le code, le débogage ne se fait pas et donne des erreurs, et même quand je retourne à l'état initial du code rien à faire. Donc je perds tout mon projet. heureusement que je ne travaille que sur les copies.
NB: toutes ces copies déboguent normalement avant toute modification.

Après modification j'ai droit à ça:
