Hello.
When the project is packaged, the following error is emitted, and the packaging fails for an unknown reason.(The version I’m using is 4.27.2.)
As mentioned in the title, we are checking the error log and trying to fix it in various ways, but just in case, we would like to hear your opinions.
I will also attach the full text of the log during packaging.
Please help me.

After 4 days of hellish bug tracking, I was able to find the source of the problem.
I’ll leave the solution for all of you who are suffering from the same problem as me.

Ultimately, there are no clear-cut solutions.
To find out where this error is coming from, I cloned the project, slowly deleted any blueprints I’d ever made (or had any idea of), cooked, and so on.
Then you have to look inside the blueprint of the cause you found and find the problem part on your own.

This issue makes me very sad.
However, it is a problem that can be overcome, so please do not give up and try.
thank you.
