Après l'installation du pilote BCM43142, le bluetooth ne fonctionne plus sous ubuntu 21.04.

J'ai récemment fait un double démarrage de Windows 10 pro et ubuntu 21.04, après avoir installé ubuntu 21. 04, quand j'ai démarré dans ubuntu tout fonctionne bien sauf le wifi à ce moment-là mon bluetooth fonctionnait bien mais il n'y avait pas de wifi alors j'ai installé les pilotes BCM43142 à partir du gestionnaire de paquets synaptic et après l'installation des pilotes quand j'ai redémarré mon système mon wifi a commencé à fonctionner mais mon bluetooth a arrêté de fonctionner et a arrêté de détecter d'autres appareils et de connecter des appareils déjà appariés j'ai déjà essayé beaucoup de choses comme installer pulseaudio, redémarrer les services bluetooth, rfkill, réinstaller les pilotes bluetooth. Rien ne fonctionne mon bluetooth fonctionne sur Windows 10 mais pas dans ubuntu svp aidez.
