STATUS_INVALID_TASK_INDEX
The task index does not identify a valid slot
STATUS_INVALID_TASK_INDEX identifies a specific Windows status in the job, task, callback, or isolation path. The supplied task index is outside the current table, generation, or scope. A stale cached index can become invalid after task teardown or reconfiguration.
Record the index together with task-set generation and owning object; reacquire it from the authoritative API.
What to preserve before changing the system
- The exact API, caller, target object, original NTSTATUS value, and any nested error or activity ID.
- For STATUS_INVALID_TASK_INDEX, the relevant process token, package/job/enclave identity, lifecycle state, and policy or mitigation settings.
- For STATUS_INVALID_TASK_INDEX, operational event logs and a timeline showing the first transition into the failing state.
