Android Question Camera2 example crashed

I use this example without any change.

Error occurred in the following function:
B4X:
Public Sub getSupportedHardwareLevel As String
    Dim jo As JavaObject = Camera.GetCameraCharacteristics(0) '<---this line caused the crash'
    Return IntToConst(jo.RunMethod("get", Array(StaticCameraCharacteristics.GetField("INFO_SUPPORTED_HARDWARE_LEVEL"))), SUPPORTED_HARDWARE_LEVEL)
End Sub
B4A 10.5, Windows 10 64Bit, Zenfone 5, Android 9

Could someone kindly show me how to fix the error? I searched the forum and I was surprised that no one else reported this problem.

By the way, the sample example works with Samsung Tab E, Android 7.1.1, and above function prints out "LEGACY".

It compiles and runs OK here, on Samsung S20, Android 11, B4A 10.5, OpenJDK and SDK versions as recommended.
From a newbie point of view, your Log seems to suggest a Permissions problem?
