Crash in Unreal Dev build With UE 4.27.2 and Wwise 2021.1.6.7774 - AsyncLoadingThread.RecursionNotAllowed.Increment()

Question

Trying to upgrade an Unreal 4.26.2 project to UE 4.27.2 and Wwise loading of the InitBank throws the following assert and callstack. Tried rebuilding all data, recompiling from scratch etc but to no avail.

Anyone have any ideas? Looks like there was a question about this already but on clicking on the suggested link the page isn't found

Assertion failed: AsyncLoadingThread.RecursionNotAllowed.Increment() == 1 [File:D:/p4/ue/Engine/Source/Runtime/CoreUObject/Private/Serialization/AsyncLoading.cpp] [Line: 3992]

I too have ran into this since updating. Still happening in 2021.1.7.

Edit:
Apparently I had a race condition causing it. I had a hard coded file path which was not getting loaded in time. Removed it to be a blueprint variable fixed the problem.

Answer 1

This issue still happens in 4.27.2 and UE Wwise integration 2021.1.8.
