Hello there @user_c1876d8f768c16781a39e6d42f29b68c9702c753f075f472157bd1!
From your provided log, it sounds like certain plugins are either not enabled, or not detected in your pack process. As a first step, please make sure that the following plugins are enabled in your project:
- Chaos Niagara
- Geometry Collection
- Niagara Fluids
After that, please double-check that said plugins are present in your .uproject file when cooking.
