Research direction

Start with archinstall/tui/ui/components.py at _exec_callback, then reproduce the Additional packages → back → exit sequence and inspect the traceback around screen dismissal. Compare the worker and event-loop behavior shown in the report. Done means the sequence exits without the RuntimeError, follow-up AttributeError, or unawaited-coroutine warnings.
