I'm not able to reproduce the auto-complete behavior you're seeing in 1.17.3. Could you provide the following logs? Could you also check if other IntelliSense features are working, such as "Find All References"?

• Logs from running C/C++: Log Diagnostics from the VS Code command palette
• Enable Logs from the language server (see https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server) and reload window and reproduce the issue.

The log said IntelliSense process crashed ,
and I have found that the problem only occurs if the Chinese (Simplified) (简体中文) Language Pack is installed,

@wangr-x Thanks for reporting this -- we have a fix at #11339 for 1.17.4 on Monday (PST, so the update may not be seen till Tuesday for some time zones). In the meanwhile, you can work around it downgrading to 1.16.3, disabling the language pack, or updating the file in your extension install corresponding to <pathTo>/.vscode/extensions/ms-vscode.cpptools-1.17.3-<osInfo>/bin/messages/zh-cn/messages.json with the contents at https://raw.githubusercontent.com/microsoft/vscode-cpptools/0ee2cd89f5e3de9a163f02a8713bbb7a7915c488/Extension/bin/messages/zh-cn/messages.json.

The issue should repro with any language pack, not just Chinese (Simplified).

We'll improve our internal update processes to prevent this type of issue in the future.

@warzone-oier @TsXor Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.17.4

version1.17.3 has been torturing me for two days。

[bobbrow]

@LiRWZ this should be fixed in 1.17.4. Can you give that version a try?

[sean-mcmanus]

@bobbrow My impression was that @LiRWZ saw the previous "Fixed with" comment and was just expressing their feelings in regards to the past 2 days before the fix was released.
