UE 5.5 project crashes on second launch

We have a workaround for now, in FMODAssetBuilder.cpp add a call to FlushAsynLoading() in the ProcessBanks() function before everything else:

void FFMODAssetBuilder::ProcessBanks()
{
    FlushAsyncLoading();
    ...
}

We are continuing to investigate the best solution for our integration.
