Start with the linked Jenkins console log and trace the failed copyArtifacts calls, especially the test.getDependency step and the win2019-x64-4 channel termination. Determine whether this failure can be safely restarted and document or implement the expected recovery behavior; done means the restartability decision is clear and verified against a comparable test run.
