@tonyjansan Could you provide the language server logs (see https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server). Does this issue also occur for a simple "hello world" project?

Update:

@tonyjansan Could you check the ~/.vscode/extensions folder and look for the extensions folder that includes ms-vscode.cpptools-1.17.5 in its name. From the vscode.cpptools folder, go to the folder bin, verify the executables cpptools and cpptools-srv exitis, and from the terminal type file cpptools to check the architecture?

Have the same problem. It started after update of VS Code done few days ago.

@MichalGuzieniuk It looks like the language server process was able to run based on your logs. Does the issue still repro whenever you launch VS Code? It could be an installation issue of the extension when VS Code was updated.

[MichalGuzieniuk]

Problem is reproducible. On each CS Code run, I got following message [Error - 6:23:33 PM] The language server crashed. Restarting...

I had the same issue, and I found someone on Reddit that posted this simple fix that worked. Update. I have now resolved this issue. Had to edit my PSModulePath environment variable and move the entry for Powershell 7 modules above the Windows Powershell entry. credit goes to Shidojin on r/vscode

Same problem here!

"Unable to start the C/C++ language server. IntelliSense features will be disabled. Error: Error: Pending response rejected since connection got disposed"

Re-assigning to @sean-mcmanus or @Colengms.

I have uninstalled all other plugins but C/C++ Extension Pack, it still not working.

[ntadej]

I also have this problem. I'm happy to help debug.

Good point! I'm also happy to help debug this!

I'm having this problem on both the 1.18.5 release version and the 1.19.1 prerelease version with the exact same call stack posted here: https://github.com/microsoft/vscode-cpptools/issues/11451#issuecomment-1836031464

[Jakeclearwater]

Can be solved by opening a powershell instance as admin and inputting: Enable-PSRemoting -Force

[georgysh]

Happens to me as well, both Insiders and normal build. OSX 13.6.4.
