I appear to have the same or similar issue. None of the C/C++ extension commands work. For example:

In the Log (Extension Host):
[2022-02-21 14:51:10.277] [exthost] [error] [ms-vscode.cpptools] provider FAILED
[2022-02-21 14:51:10.277] [exthost] [error] TypeError: Cannot read property 'ActiveClient' of undefined

The whole extension is completely unusable. Insider version:
Name: C/C++
Id: ms-vscode.cpptools
Description: C/C++ IntelliSense, debugging, and code browsing.
Version: 1.9.0
Publisher: Microsoft
VS Marketplace Link: https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools

Tried switching the release version. Still got the same problem:
[2022-02-21 14:57:25.931] [exthost] [error] [ms-vscode.cpptools] provider FAILED
[2022-02-21 14:57:25.931] [exthost] [error] TypeError: Cannot read property 'ActiveClient' of undefined

Tried uninstalling and re-installing. Still failing in the same way. So the C/C++ extension is completely broken as it doesn't load.

Hi @SmileGobo @BillDenton . Could look in the .vscode\extensions\ms-vscode.cpptools-x.x.x\.vsixmanifest in your profile directory, and tell me what the value of TargetPlatform there is? I'm curious if you're repro'ing this issue: microsoft/vscode#141696

[Colengms]

I'm not certain this issue has been addressed, but there will be a couple of fixes in 1.9.1 that might address this. 1.9.1 should be available 'really soon'.

[BillDenton]

@Colengms In my .vscode\extensions\ms-vscode.cpptools-1.9.0 in .vsixmanifest:
<Identity Language="en-US" Id="cpptools" Version="1.9.0" Publisher="ms-vscode" TargetPlatform="win32-x64"/>

Checking in the Log (Extension Host) today I also noticed another error from a different extension:
[2022-02-22 22:10:14.131] [exthost] [info] ExtensionService#_doActivateExtension beaglefoot.awk-ide-vscode, startup: false, activationEvent: 'onLanguage:awk'

I recently installed the AWK extension (beaglefoot.awk-ide-vscode). Could that be causing the problem? I'll try uninstalling it.
Update: Uninstalling the AWK extension made no difference. C/C++ extension is still completely broken. A bit of a show stopper as 99.9% of my work is in C++ or C.

@bobbrow @Colengms any updates? The extension is unusable. I can't switch to the Clangd extension as our build system (scons based) doesn't produce the compiler json database. Tnanks.

[Colengms]

Hi @BillDenton @SmileGobo . 1.9.1 has been released. Could you check if this issue is still reproducible with 1.9.1?

[xjrjyy]

In my VS Code, cpptools can't use it with clangd(because of the Intelli Sense Engine setting)

[error] Error: Do not activate the extension when IntelliSense is disabled.

[BillDenton]

@xjrjyy As far as I can tell the Microsoft C/C++ extension is mutually exclusive with clangd extension. As the Microsoft extension wasn't starting I tried the clangd extension (after disabling the Microsoft extension).
@Colengms after upgrading to 1.9.1 is now working again. However, it did start working with just a window reload. I had to shut down VS Code and start again. I found that the IntelliSense had been disabled (like @xjrjyy). After re-enabling and restarting VS Code is now working. Glad to have it back again. It was quite a pain to navigate the code without it. Thaks.

@Colengms Hi! I'm make full reinstall code and plugins pack, but have same problem. Answer on your request
TargetPlatform="win32-x64"
PS later try new version.
PPS after reinstal not reproduced.

[Colengms]

It sounds like this issue was addressed with 1.9.1. :) Closing.
