I recently bought this bundle https://www.unrealengine.com/marketplace/en-US/product/the-medieval-mega-bundle

I get this error when I package a specific map in the bundle (during cooking), I contacted the author of the tool and his computer builds it just fine, he even gave me a copy of his local project and I receive the same error on it. I reinstalled the engine (5.4.4) and it still gives the same error, every time I build the project, the numbers of the error are different.

How can I fix this?

The error:

PackagingResults: Error: Local file ‘:?#:85720’ format is not compressed
UATHelper: Packaging (Windows): LogInit: Display: LogZenSerialization: Error: Local file ‘:?#:85720’ format is not compressed

PackagingResults: Error: Unknown Cook Failure

I found the solution. The culprit was a static mesh being packaged and included in the level. I deleted the static mesh and replaced its references with another and it worked.
