Why camera does not work versions that lower than api 33?

Question

I have camera in my project to take video with voice and save this in device folder. I am using Dexter library for permission check. Camera open on device with higher than api 32. but lower api 33 it's not working. I check this in debug mode that's not work in Dexter code if it's granted or not. What's wrong here?

I added these code for permission api lower than 33. And camera works now. So I just added answer who has same error with me.

private fun checkPermissions(permissions: Array<String>): Boolean {
    for (permission in permissions) {
        if (ContextCompat.checkSelfPermission(requireContext(), permission) != PackageManager.PERMISSION_GRANTED) {
            return false
        }
    }
    return true
}
private val requestMultiplePermissions =registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions())
{
    permissions ->
    permissions.entries.forEach {
        it
    }
    if (permissions[RECORD_AUDIO] == true && permissions[CAMERA] == true) {
        startCamera(CameraSelector.DEFAULT_BACK_CAMERA)
    }
}
