Camera2Basic failed to open camera normally

After I import Camera2Basic into Android Studio and run it (My device only has front camera)

for the first time, camera opened normally, then no matter I exit camera, clear the cache/data, uninstall the APP and reinstall it, camera still failed to open again. log from Android Studio is as below:

It seems stunk in the starting window, in the left-top window, it shows 'Front JPEG (0)'

Reproduisez l’échec au démarrage de Camera2Basic dans Android Studio sur un appareil ne disposant que d’une caméra frontale, en commençant par CameraActivity et le chemin d’ouverture de la caméra indiqué par le log. Comparez le premier lancement réussi aux lancements suivants et utilisez le log de démarrage signalé pour identifier l’endroit où l’ouverture s’arrête. C’est terminé lorsque l’exemple ouvre de manière fiable la caméra frontale après avoir quitté l’application, effacé les données ou réinstallé l’application.
