How to fix disappearing landscape in 5.3 Electric Dreams?

Hi all,

Please, do you know why, in UE5.3, the landscape is disappearing when the game is packaged? Not in all projects, so you can check it specifically when packaging the Electric Dreams demo.

I need to stay in 5.3, and I have already tried tons of options and combinations read over the internet. Have you faced this issue and found a solution or workaround?

Thank you very much!
