Please follow the below format,
foreach ($request->txt_language as $language => $l){
$data = new Language;
$data->candidate_id => $candidateID,
$data->language => $request->txt_language[$language],
$data->reading => $request->txt_reading[$language],
$data->writing => $request->txt_writing[$language],
$data->speaking => $request->txt_speaking[$language],
$data->save();
}
Hope this would fix your issue. Let me know if you face further issue.

Try this :
public function addLanguage(Request $request){
$candidateID = Auth::guard('candidate')->user()->id;
if(!empty($candidateID)){
if (count($request->txt_language) > 0){
foreach ($request->txt_language as $language => $l){
Language::create([
'candidate_id' => $candidateID,
'language' => $l,
'reading' => $request->txt_reading[$language],
'writing' => $request->txt_writing[$language],
'speaking' => $request->txt_speaking[$language],
]);
}
}
return redirect('/candidate/referencesForm')->with('success','Language Information Save Successfully..');
}
abort(404);
}
