This code belongs to a fragment which shows the user's current location.After getting location when I want to go back to previous fragment App crashes.Logcat says error is happening here : "val geocoder = Geocoder(requireContext(), Locale.getDefault())" If anyone could assist me, I would greatly appreciate it

I used 'requireActivity' instead of 'requireContext' but didn't work
I changed the code in this way :
val geocoder = context?.let { Geocoder(it, Locale.getDefault()) }
in this methode :
fun updateAddressUI(location: Location) {
map.isMyLocationEnabled = true
val addressList: ArrayList<Address>
val geocoder = context?.let { Geocoder(it, Locale.getDefault()) }
if (geocoder != null) {
addressList = geocoder.getFromLocation(
location.latitude,
location.longitude,
1
) as ArrayList<Address>
lat = addressList[0].latitude
long = addressList[0].longitude
}
