Unreal Engine multi process cook crashes

0 votes
Hey, I'm attempting to enable Multi Process Cook. I consistently get crashes when attempting that kind of cook with Wwise assets. Single process always works. I have read the known issues here (https://www.audiokinetic.com/en/public-library/2024.1.4_8780/?source=UE4&id=using_knownissues.html), I have tested both versions 2024.1.3 and 2024.1.4. I have used the WwisePackagingSettings bPackageAsBulkData set to true. The below crash happens regardless. I can translate the non-english part, it says that the file cannot be accessed by the process, because it is used by another process. I'm using UE 5.5.

Has anyone got it to work? I was wondering why are the *.wem files created with the option turned on, since the option comment says it should be using uasset files.

I can add more info, there are 2 ways this is caused. The below are relevant parts of the log in chronological order. One is:

So write when other processes hold the file read-open, and two:

Which is an attempt to delete the file held by other process (error code 32 means other process uses the file)
