Any idea?
I have tried with Async on and off in the project settings

I have the same problem.
Since i have some folders on always cook mode, i made myself a DebugAllAssets function to log what assets are available (modding ftw).

While iterating and loading these assets i get a quite similar stacktrace from LoadPackageInternal to the failed assertion.

It happens to me only in the packaged game though.

Please post on the answerhub so it can be tracked… Thanks.

@BagmanPT

Fix (which worked for me): turn off event driven loading. The option is right below the async loading entries.

Thanks @Algorithman! I had the same issue and turning off “Event Driven Loader Enabled” in the “Packaging Settings…” fixed it for me too. Btw, @BagmanPT, please link the AnswerHub ticket in this thread.

Thanks, this solved my crash as well.

I disabled “Event Driven Loader Enabled” under Engine -> Streaming. But it wasn’t under Project -> Packaging like you guys are pointing out.

Any ideas how to work around this? Should I build the engine from source?
