I have the same/similar issue, same error message at least (os Catalina, MacBook Pro retina late 2013), Wwise 2019.2.2.7275, Unreal 4.25 & 4.23.
Is there any work around or will I just need to wait until Wwise updates to 2019.2.3? if so any idea the kind of timescale that will be?
for the record it does work fine in Unity.
