I’m far from an expert here but I tried cooking a project that failed and just by going through the log, looking for any instance of “LoadError”, seeing what file it was referencing and making sure I got rid of them all or placed them in the expected spot fixed the issue - looks like you have some in your log.
I found that my projects would cook properly once I made sure there were no errors.
Some of the files had names that were too long so I shortened them, I also right-clicked the content folder in UE4 and did ‘fix up redirectors’. This seems to just help things in general. Redirectors | Unreal Engine Documentation
Hope you manage to fix the issue!
