…te_task Replace the bare `next()` lookup with an explicit role match that raises a ValueError naming the missing role and the available roles, instead of the cryptic StopIteration. Also build Task kwargs from a copy of the config dict so reusing the same dict across Crew constructions no longer raises KeyError on the second use. Closes crewAIInc#6439 (bugs 1 and 4).

A side-effect after_kickoff callback that does not return the result used to replace the crew result with None, crashing downstream code. Guard both the sync kickoff and akickoff loops so a None return leaves the prior result untouched while a returned value still replaces it. Closes crewAIInc#6439 (bug 2). Co-authored-by: CommandCodeBot <noreply@commandcode.ai>
An async task callback on the synchronous execution path called asyncio.run() unconditionally, crashing with "asyncio.run() cannot be called from a running event loop" when execute_sync ran inside an already-running loop (Jupyter, akickoff). Route awaitable callback results through the same worker-thread pattern as agent_utils.py: run them in a thread with their own loop and a copied context when a loop is already running; otherwise asyncio.run directly. Closes crewAIInc#6439 (bug 3). Co-authored-by: CommandCodeBot <noreply@commandcode.ai>
A task callback returning an asyncio.Task or Future already bound to the running loop passed the isawaitable check and the worker-thread handoff, then crashed on the worker loop with a cross-loop RuntimeError - the same crash class crewAIInc#6439(3) was meant to fix. Mirror the guard in utilities/agent_utils.py: reject asyncio.Future values with a clear TypeError before the thread hop. Also add missing async coverage: akickoff after_kickoff result-replace branch, and the crew.task_callback async path on the sync execution route.

In `@lib/crewai/tests/task/test_async_task.py`:
- Around line 236-346: The callback regression coverage only tests successful
coroutine results; extend the async callback tests around Task.execute_sync to
cover callbacks returning an asyncio.Task and an asyncio.Future, with one test
for each result type asserting that execute_sync raises TypeError. Reuse the
existing callback and mock setup while preserving the current success-path
tests.
In `@lib/crewai/tests/test_crew.py`:
- Around line 2222-2235: Update the replacement callback tests so each callback
returns a distinct adjusted CrewOutput without mutating its input, then assert
kickoff returns that distinct output with the adjusted content. Apply this to
lib/crewai/tests/test_crew.py lines 2222-2235 and
lib/crewai/tests/crew/test_async_crew.py lines 262-300; both sites require the
direct test change.

…utput Address CodeRabbit feedback on PR crewAIInc#7028: - Add regression tests asserting execute_sync raises TypeError when a task callback returns a loop-bound asyncio.Task or asyncio.Future, covering the guard added in the sync-path callback fix. - Make the after_kickoff result-replacement tests return a distinct CrewOutput instead of mutating the callback input, so they fail if production ignores the callback return value.

Summary
Fixes #6439 — four error-handling defects in Crew config-based construction and callback execution that produced cryptic runtime failures.
Before: a task referencing an unknown agent role raised a bare
StopIteration; reusing the same config dict across twoCrew(config=...)constructions raisedKeyError: 'agent'; a side-effectafter_kickoff_callbacksfunction that didn't return the result replaced the crew result withNone; and an async task callback on the synchronous execution path crashed withasyncio.run() cannot be called from a running event loopinside Jupyter/akickoff().After: the unknown-role case raises a
ValueErrornaming the missing role and available roles; the caller's config dict is no longer mutated; aNone-returningafter_kickoff_callbackspreserves the crew result; and async task callbacks run safely from the sync path, using a worker thread when an event loop is already running. Loop-bound Task/Future returns are rejected with a clearTypeError(mirroringutilities/agent_utils.py), so the crash class the fix targets cannot resurface.Changes
