LogOutput Device Error when packaging

Hi guys,
so when I try to launch my game in the project launcher with shipping and cooking by the book settings I get few errors and my build fails. I have tried to move my project to another file but it doesn’t work.
If anyone knows what is happening please answer

Okay so I fixed my problem in the meantime. It was just problem with some bones and animation not matching

Hey and what means “problem with some bones and animation not matching” ?
I have the same error and I have absolutely no idea for what I should search / what I could try to debug.

Do you have any suggestions? What is the LogOutput Device? What does it doing?
Why is this since > 4.17 and < 4.17 everything works fine with cooking.
