Unreal engine hangs during unloading sub level that contains UAkAudioEvent.

Unreal engine hangs after requesting unloading streaming sub level that contains UAkAudioEvents

most of crashes has similar call stacks like below

and we've tested with some of features off like "Split Switch Container Media", but failed to fix it

and how could we access AK::SoundEngine::UnloadBank or CAkThreadedBankMgr::WaitForSyncOp implementation codes.

just Installing Wwise doesn't help for us to access above those codes (only header files we found)

please give us some advice
