[C++] Deadlock in CSV AsyncThreadedTableReader destructor #48741
Description
Describe the bug, including details regarding any error messages, version, and platform.
When reading a CSV file encounters an early error, and the AsyncThreadedTableReader is only kept alive through the chain of futures and their callbacks, the ~AsyncThreadedTableReader destructor will be executed at the end of a TaskGroup task and try to wait for the TaskGroup itself for finish. This will obviously deadlock.
