App crashing due to this error but function found based on error logs seem fine to me

Question

Im dealing with this type of issue for the time and been stuck at this for weeks now. I already posted about finding location of error & tried to solve on my own after finding however I don't know what might be causing error here. Everything seems to be fine. Here's the error log file code:

So based on this error, I found this code:

func initAudio(_ alertType: String) {
     if self.checkPermission() == 0 {
          if AVAudioSession.sharedInstance().outputVolume < 0.0625 {
              let soundid = kSystemSoundID_Vibrate
              AudioServicesPlaySystemSound(soundid)
              self.deleteAllRecordings()
          }else{
              self.alerttype = alertType
              self.deleteAllRecordings()
           }
       }else if self.checkPermission() == 1 {
           gotoPermission(1)
       }else{
           gotoPermission(2)
       }
}

Im totally lost here what might be wrong. Is it caused by AVAudioSession? or the two functions, self.deleteAllRecordings() or gotoPermission(1) or gotoPermission(2)?

Here's the code for deleteAllRecordings() just in case:

func deleteAllRecordings() {
        print("\(#function)")

        if self.recorder != nil {
            self.recorder.stop()
        }
        let docsDir =
            NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]

        let fileManager = FileManager.default

        do {
            let files = try fileManager.contentsOfDirectory(atPath: docsDir)
            let recordings = files.filter( { (name: String) -> Bool in
                return name.hasSuffix("wav")
            })
            for i in 0 ..< recordings.count {
                let path = docsDir + "/" + recordings[i]

                print("removing \(path)")
                do {
                    try fileManager.removeItem(atPath: path)
                } catch {
                    NSLog("could not remove \(path)")
                }
            }
            self.record()

        } catch {
            print("could not get contents of directory at \(docsDir)")
            print(error.localizedDescription)
        }

    }

and code for gotoPermission():

func gotoPermission(_ grant: Int) {
    if grant == 1 {
        self.askForPermission()
    } else {
        if !self.initiatorStatus.InAlertMe && !self.initiatorStatus.InTimedAlert{
            self.beepStartPlayer.play()
            DispatchQueue.main.async {
                Timer.scheduledTimer(withTimeInterval: Double(User().cUser.RecordSeconds), repeats: false, block: { _ in
                    if self.initiatorStatus.InAlert == true {
                        self.startBeep()
                    }
                })
            }
        }  
    }
    
}

Is there something that might cause te crash in above code? According to log file, this is where the error occurs.
