Visual Studio2017のSystem.AggregateException15.6.2

Visual Studio 2017とReSharperをクリーンインストールしましたが、Visual Studioの場合は15.6.2に、ReSharperの場合は2017.3.3にアップグレードすることにしました。残念ながら、今ではVisualStudioで次のようなポップアップが表示されてクラッシュし続けていますvisual studio an exception has been encountered. this may be caused by an extension。

そのため、ReSharperを無効にしましたが、続行され、エラーログは次のようになります。
