Multiple project packaging errors

Hello everyone. Who can tell you what these errors are talking about? Couldn’t find any documentation.

What I was doing:

  • The problem appeared unknown when, the project was not collected for about half a year. Previously, everything was ok.
  • There are no problems in the BP, everything compiles successfully, runs, jumps, i.e. the game is working
  • The project was destroyed some time ago. I was creating a new project and transferring all the content from the Content folder to the new project. Is it possible because of this? If so, how to understand, there are hundreds of functions in it…
