crash on oo2tex_win64_2.9.12.dll during cook stage

We are currently using Unreal Engine 5.4 and are encountering the following crash during cooking.

While investigating, we found this issue on the Unreal Issue Tracker:

https://issues.unrealengine.com/issue/UE-229064

The page suggests that the issue has been fixed, referencing commit 37662774.

However, when checking the official GitHub repository, the only related change I can find is this commit:

https://github.com/EpicGames/UnrealEngine/commit/f3864e3643f99cdbde79bb473bc2fa04b5305678

This appears to be a revert rather than the actual fix.

My question:

Which commit actually contains the real fix for this issue?

Is the original fix available somewhere, or was it reverted intentionally?

I’m trying to determine the correct patch to apply to resolve this cooking crash.

Thanks in advance for any clarification.

Hi Tyrone,

The crash you are seeing is from the Oodle compression library, which is distributed separately from the engine. The public issue tracker merely suggests that the fix was verified against an engine build from that CL (it’s a bit hard to tell). The fix for this particular crash was released in Oodle 2.9.13, and your current version is 2.9.12. You will need to upgrade your Oodle library to fix this crash. If you need help with that, please don’t hesitate to let me know, and I can give you some extra guidance.
