Visual Studio Integration - Error in PSES

I'm seeing an error in PSES when integrating with VS. I'm not sure if it's a problem with my integration or with PSES. PSScriptAnaylzer is showing suggestions but IntelliSense doesn't work.

PSES 3.3.1
VS 17.1.5

Error in PSES log.

PsesInternalHost.CurrentFrame と CurrentRunspace から始め、次に textDocument/hover リクエストについて SymbolsService.FindSymbolDetailsAtLocationAsync を追跡します。PSES 3.3.1 と VS 17.1.5 を使用して Visual Studio 統合を再現し、PSES と Visual Studio のログを使います。hover と IntelliSense が空の Stack で失敗しなくなれば完了です。
