Unable to see any VARIABLES or WATCH variable values

Ninguém assumiu esta issue ainda.

Issue Type: Bug

I am using Visual Studio Code with the Microsoft C/C++ extension to debug a native 64 bit Windows application, compiled using Visual Studio 2019, latest update. Sometimes you cannot see any local variables, the display just shows this in red:

Error processing 'variables' request.

The watch window shows: An unspecified error has occurred.

Please see the screen show.

Sometimes when you step through or over code, you temporarily see this status, and it goes away again. But in the last few weeks, especially after the last few C/C++ extension updates, it seems far more common and does not recover, unless you restart the debugging session, and then maybe it will work again for some time.

PLEASE HELP. Sadly the code project is massive, not easy to share, and it does not always happen. What extra information can I provide, is there some sort of log file, or way to debug this extension.

Visual Studio Code has been work so well, and this used to never happen, but in recent times this has become more common.

Comece reproduzindo os valores ausentes de Variables e Watch na extensão VS Code C/C++ ao depurar o aplicativo nativo de Windows de 64 bits relatado. Colete os logs da extensão e do depurador solicitados na issue e compare o comportamento durante a execução passo a passo e em sessões reiniciadas; o trabalho estará concluído quando uma causa reproduzível for identificada e a inspeção confiável de variáveis for restaurada.
