Hey there, sorry to hear you're stuck with this frustrating VSCode glitch after an update—let's work through some more targeted fixes since the steps you've already tried didn't resolve things.

Here are additional steps to test out: #

• Full VSCode Cache Reset
  Leftover cache files from updates often cause odd, hard-to-track issues. Let's do a proper reset:

  1. Fully quit VSCode (make sure no background processes are running—on Mac, use Activity Monitor to kill any "Code" processes)
  2. First, backup your user settings: copy ~/Library/Application Support/Code/User/settings.json to a safe location
  3. Delete the Cache and CachedData folders inside ~/Library/Application Support/Code/
  4. Restart VSCode and check if the error pops up before reinstalling any extensions

• Verify MinGW Environment & C/C++ Configs
  System updates can sometimes disrupt path variables or extension configurations:

  1. Open your terminal and run gcc --version and g++ --version—if these don't return valid version info, your MinGW path isn't properly added to your system's PATH variable. Fix that and restart your terminal/VSCode.
  2. In VSCode, open the C/C++ configuration UI (press Ctrl+Shift+P then search for "C/C++: Edit Configurations (UI)"):
     • Confirm the Compiler Path points directly to your MinGW gcc/g++ executable (e.g., /usr/local/bin/gcc or C:\MinGW\bin\gcc.exe on Windows)
     • Make sure the IntelliSense Mode matches your MinGW architecture (e.g., gcc-x64 for 64-bit MinGW)

• Reset Build Task Configuration
  A corrupted tasks.json could be the culprit behind slow build task retrieval:

  1. If you have a .vscode/tasks.json file in your project, delete it
  2. Regenerate a fresh build task: press Ctrl+Shift+P, search for "Tasks: Configure Default Build Task", then select the appropriate C/C++: g++ build active file or gcc option
  3. Try running the build task again to see if the delay improves

• Downgrade the C/C++ Extension
  The latest extension version might have compatibility issues with your setup:

  1. Open the VSCode Extensions panel, find the "C/C++" extension by Microsoft
  2. Click the gear icon in the bottom-right of the extension card, then select "Install Another Version..."
  3. Pick a slightly older, stable version (versions around 1.14.x-1.16.x tend to be reliable for most setups)
  4. Restart VSCode after installation and test

• Update System & VSCode
  Outdated system software or VSCode itself can create compatibility gaps:

  1. Make sure your macOS is fully updated (System Settings > General > Software Update)
  2. Update VSCode to the latest version (Help > Check for Updates)

If none of these steps work, grabbing the exact error message you see on startup, plus any logs from the VSCode Developer Console (Help > Toggle Developer Tools > Console tab), will help narrow down the root cause even further.
