Minecraft Windows 10 Edition Béta

[Capfamily]

Bonjour

Depuis quelques jour, Minecraft plante au lancement. Aucune modification matérielle ni logicielle faite sur le PC. Dernière version de Java installée.

J'ai l'écran Mojang qui s'affiche et au bout d'une vingtaine de seconde celui ci se ferme.
J'ai un fichier log qui a été crée :
