Unreal Engine XboxOne game crashes loading .bnk files if launched with Cook server

0 votes
I'm using Unreal engine 4.19 with Wwise integration.

If I do a Cooking By the Book build, the game runs normally, but with the Cook server and Cook on the fly, it crashes trying to load a .bnk file.
In particular the engine function FNetworkPlatformFile::EnsureFileIsLocal issues a fatal error while CAkUnrealIOHookDeferred::PerformOpen tries to read the file size with IFileManager::Get().FileSize(*FilePath);

The cook server log last line does list that bank:
LogFileServer: Display: Read S:/SK/Projects/SK/Content/WwiseAudio/XboxOne/Lvl02_Generic.bnk, 362103780 bytes
that is also pretty big. May the size of the file be related to this problem ?

If anyone has info or hints on the matter, it would be very welcome because being unable to debug with cook on the fly is a major issue for us.
Thanks
