Hello everyone. I had been using UE 5.4.4 to create an interactive interior walkthrough for a client. I previously packaged the project using the project launcher profile and it packaged successfully, so did other projects.
Recently, when I am trying to package the project again, after making a few changes like adding some swappable furniture, the project is no longer packaging, and it is giving a weird set of errors.
Here is a part of the log with error:

Can anyone please help me understand why the project is not packaging, even with the project launcher?
