My camera app keeps crashing after updating to android 11.It does not open at all and i have noticed my flashlight at the quick settings has also been greyed out which says flashlight is currently in use.I tried downgrading to android 10 and the problem stil persists.Any flashlable tweak to help resolve this issue will be appreciated.
