Why a packaged project works halfway?

Hello! Help, please, to solve the problem with the project packer, perhaps. After I package my project, half of the things just don’t work. Link to drive with problem visualization: Help2.mp4 - Google Drive. All buttons work on the same principle: the result of a hit under the cursor is analyzed, if the hit object contains a certain blueprint interface, then the interaction function is called (I also use the enhanced input system plugin). In the viewport and in the standalone game window, everything works, but not in the final version after packaging. Thanks in advance!

In general, this can be somehow solved, but this system does not make any sense, you just need to mix the ui with meshes, and not make complex logic using collisions
