### 前提・実現したいこと

UnityにてAndroidの64bit版で正常に動作するものを出力したい。

### 使用環境

  * MacOS Mojave 10.14.6
  * Unity 2018.1.6f1, 2018.1.9f2, 2018.2.21f1, 2018.3.14f1
  * UTNotifications - Professional Local & Push Notification Plugin 1.8.2
  * PlayMaker 1.9.0.p18
  * Prime31 iOS and tvOS StoreKit In App Purchase Plugin 3.2
  * iTween 2.0.10
  * SpriteStudio 6 Player for Unity 1.1.19

### 発生している問題・エラーメッセージ

最終結果はUnityにてAndroidの64bit出力を行いたいです。  
「edit」→「project setting」→「player」にて「other settings」の  
「Scripting Backend」で「il2cpp」を選択、「ARM64」にチェックをすれば64bitで出力できるところまでは、調べて把握しました。  
そこで上記の通り設定し、ビルドを行ったところ  
初期の状態でエラーが出たので、各アセットを最新のものでインポートしなおしたところ  
ビルドはできる状態になりましたがタイトル画面から次の画面（ローディング画面）へ遷移したところで  
まったくAPIへ通信を行わなくなる状態になりました。  
Unityのバージョンを上述の通り2018.1.6f1→2018.1.9f2→2018.2.21f1→2018.3.14f1とUnityHUBを利用し上げていったのですが、  
2018.1.9f2では2018.1.6f1と同様ビルドはできるのですが、通信を行わない状態  
2018.2.21f1以降のバージョンでは、以下のエラーが出る状態です。  
この問題を解決したく思っております。

### 試したこと

UnityHubでバージョンを一つずつ上げ、ビルドを試してみました。

question
android c# unity3d
タイトル画面より遷移後、API通信を行わなくなる原因を突き止めたい。


SQLite4Unity3dが古く64Bit対応ではありませんでした。
