### Additional context

_No response_

Start by reproducing the activate.validateAndInstallBinaries action on Windows with the supplied user settings JSON, then inspect the reported VS Code configuration-writing call stack. Done means the user settings save successfully and binary validation or installation no longer produces the configuration editing error.
