Start with the linked workflow run and the VS Code extension E2E (launch-profiles) shard, then compare the three listed occurrences across Linux and Windows jobs. Job logs are unavailable in the report, so determine the underlying failure before changing anything. Done means the flaky cause is addressed and the launch-profiles shard passes reliably.
