crashes on startup
Type: Bug
using latest version 1.19.9 and tried with 1.18.5. C++ crashes repeatedly on startup and is therefore diabled by vs code. This report was generated using the bisect so I hope it gives the information required to fix.

Could you please provide more information about what is causing the crash? Does it happen whenever you open any .cpp file? Could you provide a copy of your c_cpp_properties.json file? This should be in the .vscode folder
Hi thanks for replying. It was occurring whenever I opened VS code.
I have some folders in the workspace that was being opened when i opened vs code - raspberry pi/pico sdk etc but none with my own C++. (For context I'm just getting started with this dev environment on the mac and with the pi/pico.)
There's no file by that name in .vscode in my home folder:

@m76589 The c_cpp_properties.json file would exist in your workspace folder's .vscode folder, but it won't exist unless you generated it via a command like C/C++: Edit Configuration. Without it, it uses defaults.
With 1.20.1, we've added crash call stack logging if you check the Help->Toggle Developer Tools->Console.
Otherwise, can you set C_Cpp.loggingLevel to "Debug" and check the "C/C++" pane logging to see what output occurs before the crash? Typically a crash restart will generate another "initialize" message.
I've split my initial workspace into two smaller ones and the issue seems not to occur (only tested briefly).
From the debug info in the console there's some information that shows before the crash about something being used before initialized. The crashes occur when i open the workspace.

@m76589 Can you try with 1.20.2 (pre-release)? It may be fixed in there or the crash call stack may be shown in the Console tab after using the 'Toggle Developer Tools' command.
@m76589 Also, I think Attempting to use languageClient before initialized is just a symptom of the cpptools crash. Were you able to get any C/C++ logging to show up?
Also, if you don't get any logging, can check if you have /Users/mm/.vscode/extensions/ms-vscode.cpptools-1.19.9-darwin-x64/bin/cpptools (or whatever the version is) and the file is runnable?
Hi Sean Thank you for your help. I think these are the things you have asked for:

Hi @m76589 . Did your repro involve multiple workspace folders in a multi-root workspace that may have resolved to the same folder, due to a symbolic link in the file system, or some other reason why multiple paths wind up referring to the same folder? We believe we've identified a problem, but it would seem specific to multiple workspace folders in a workspace resolving to the same path. If that is not your scenario, there may be more for us to investigate.
Yes - I have/had two folders that were "added to workspace" that were sub folders of another top level workspace folder. However I didn't check whether there were any sym links in the folders. They were raspberry pi pico examples from github - so it's possible. In general I add subfolders to the workspace a lot, due to the way folders open on the left when also opening files.
Hi @m76589 . To clarify, the issue we've identified is specific to exactly the same 'workspace folder' being present multiple times in a multi-root workspace, at the root level. You would see exactly the same contents in both (or all such) workspace folders. Normally, it's not possible to add the same folder to a multi-root workspace twice, though VS Code does not appear to resolve symbolic links and can allow this to happen if the paths differ due to containing a symbolic link. If you can confirm whether or not this scenario is indeed what occurred in your repro, that would help us determine if we've addressed the issue or not.
hi. Thanks for looking into this. Unfortunately I'm not with my laptop for two weeks now. If you want to try to reproduce... The folders i had open in the workspace were github repos for getting started with raspberry pi pico development. These were, from memory: pico-sdk, pico-extras, pico-examples, and pimoroni-pico. I had two of the sub folders open too: blink, helloword. That might suffice.
@m76589 We think this is fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.20.3 , although we weren't able to repro your exact scenario so it's possible there could be another failure after the fix we made.
