Xamarin iOS應用程序，只要它被推出

Question

Windows環境崩潰。但是，在應用最新的Xamarin更新（在Windows和Mac上）之後，該應用在啓動後立即在iOS上崩潰。

以下是我在Visual Studio中的輸出窗口中看到：

我已經設法通過更新我的項目中的所有軟件包來解決這個問題，除了Xamarin.Forms，我保留在版本2.3.4.231由於這個錯誤[1]。更新軟件包後，重建所有爲我工作的項目。如果它不適用於您，請在再次重新構建之前嘗試刪除bin和obj文件夾。 PS：當更新Xamarin.Forms時，確保它在所有項目中都是相同的版本（共享，iOS和Android）。
