Hi all, I’m struggling for a few days now with the Particle workbench extension in MS Visual Studio Code. A couple of months ago everything was working flawlessly, but with the latest versions it seems like the extension is not executed correctly on my Mac. **Symptoms:** - When I click on the Particle workbench icon on the left menu bar, I only see an empty screen and not the usual “welcome” screen with all options: - When I type Shift + CMD + P and select any Particle command, I get an error message in the lower right corner (e.g. “Command ‘Particle: Login’ resulted in an error (command ‘particle.login’ not found))” This is completely blocking me as I’m unable to build any updates or new versions of my Particle firmwares. **What I tried so far:** - Update everything to the latest version (see below) - Uninstall Particle workbench extension and install it again - Uninstall MS Visual Studio Code and install it again - Install the Particle workbench SW-package including MS Visual Studio Code from the Particle website **These are the SW-versions I run:** - Mac OS v10.15.6 - Particle CLI v2.7.2 - Visual Studio Code v1.47.2 - Particle Workbench v1.12.1 Unfortunately, I haven’t found a thread from someone experiencing the same issues AND fixing it ([this was not helpful](https://community.particle.io/t/issue-particle-workbench-welcome-screen/53448/7)). In case I missed something, kindly let me know which one might help in my case. Many thanks in advance for your advice and help! Regards, Tim ---

@ruKe if you haven't already, please try these suggestions: > [@\[ISSUE\] Particle workbench welcome screen?](https://community.particle.io/t/issue-particle-workbench-welcome-screen/53448/6): > > It shows the “particle workbench: welcome” in the heading on the sidebar, but no window anymore. thinking hm. that’s super-weird. couple of things you could check: from VSCode’s main menu, select “Help” \> “Toggle Developer Tools” then when that panel appears, switch over to the “console” tab, try to launch the “Welcome” screen, and look for any interesting errors from VSCode’s main menu, select “View” \> “Output”, then try to launch the “Welcome” screen, and then cycle through the vari… ...and report back with your findings. additionally, can you share the output of these commands: ```auto ls -la ~/.vscode/extensions/ ``` ```auto ls -la ~/.particle/ ``` ```auto ls -la ~/.particle/toolchains ``` thanks 🙏 ---

@m_m thanks for reaching out to me! See below the results, I hope this is more helpful to you than it is to me 😉 > From VSCode’s main menu, select “Help” \> “Toggle Developer Tools” then when that panel appears, switch over to the “console” tab, try to launch the “Welcome” screen, and look for any interesting errors. This is what I get: ```auto Activating extension 'ms-vscode.cpptools' failed: Cannot find module '/Users/Tim/.vscode/extensions/ms-vscode.cpptools-0.29.0/dist/main' Require stack: - /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/loader.js - /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap-amd.js - /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap-fork.js. _logMessageInConsole @ /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:4279 /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:4279 Cannot activate extension 'Workbench Core' because it depends on extension 'ms-vscode.cpptools', which failed to activate. _logMessageInConsole @ /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:4279 /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:4279 Cannot activate extension 'Arduino' because it depends on extension 'ms-vscode.cpptools', which failed to activate. _logMessageInConsole @ /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:4279 /Users/Tim/Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/workbench.desktop.main.js:1670 ERR No application in the Launch Services database matches the input criteria.: Error: No application in the Launch Services database matches the input criteria. ``` > From VSCode’s main menu, select “View” \> “Output”, then try to launch the “Welcome” screen, and then cycle through the various logs (look for the drop-down menu in the panel toolbar top-right) and look for any interesting errors.

hm. ok, that does shine a bit more light on things - thanks 👍 here’s the root cause: ```auto Activating extension 'ms-vscode.cpptools' failed: Cannot find module '/Users/Tim/.vscode/extensions/ms-vscode.cpptools-0.29.0/dist/main' Require stack: ``` workbench depends on that extension (as do many others as you can see) so it fails to load as well. a quick scan of the issues over in [https://github.com/microsoft/vscode-cpptools](https://github.com/microsoft/vscode-cpptools) shows a few perhaps related items: > > > Type: General > Input information below > Please review existing issues and our documentation at https://github.com/Microsoft/vscode-cpptools/tree/master/Documentation prior to filing an issue. > Describe the bug > > OS and Version:... > > > Type: LanguageService > Describe the bug > OS and Version: 5.3.0-28-generic #30~18.04.1-Ubuntu > VS Code Version: 1.42.1 > C/C++ Extension Version: 0.26.3 > Other extensions you installed (and if the issue... TL;DR - try this: 1. disable all extensions ([docs](https://code.visualstudio.com/docs/editor/extension-gallery#_disable-an-extension)) except for these: ```auto ms-vscode.cpptools marus25.cortex-debug particle.particle-vscode-core particle.particle-vscode-pack particle.particle-vscode-snippets particle.particle-vscode-theme ``` 1. if you are on a corporate network with unknown restrictions, etc. and able to, try connecting from a different, less locked-down network (iow, let’s rule out proxy-related weirdness if we can) 2. try reinstalling (docs: [1](https://code.visualstudio.com/docs/editor/extension-gallery#_uninstall-an-extension), [2](https://code.visualstudio.com/docs/editor/extension-gallery#_install-an-extension)) and / or downgrading ([docs](https://code.visualstudio.com/updates/v1_30#_install-previous-versions)) the `ms-vscode.cpptools` extension let me know how it goes 🙏👍 ---

@m_m thanks for looking into it! Uninstalling `ms-vscode.cpptools` and installing it again finally did the trick for me: after that, the installation of the particle workbench took much longer than just a few seconds during my previous tries. I guess w/o `ms-vscode.cpptools` working properly, even the installation of the particle workbench isn’t working as it should. Anyway, thanks a lot for your help 🙂 ![Bildschirmfoto 2020-07-20 um 21.18.39](https://us1.discourse-cdn.com/flex026/uploads/particle/original/3X/7/7/77eaf7c8354fded1905aa3052cf0d5d13a6f01a8.png)
