Answer

This happens when a project is indexing in progress, and then VS Code is updated and restarted. The reason is that the process intellij-server is not killed properly, so the indexing directory is locked. To fix this issue:

1. Close VS Code;
2. Kill all processes named intellij-server
   • On macOS or Linux, use this shell cmd: pkill intellij-server
   • On Windows, open Task Manager to kill the process named intellij-server ILSIJS (console launcher) in the Background Processes section by pressing Ctrl + Shift + Esc, navigating to the Processes tab, and kill this process.
3. Start VS Code again.
