Error Loading Private UEFN Code

Whenever I attempt to load into my UEFN private code, I get an error code #1. It says it is unable to generate content. I only have UEFN access every Tuesday, Thursday, and Friday for an hour at school due to me not having a PC at home and me not being able to work at home annoys me. I feel it may due to me adding HLOD layers to my map. Past versions without these layers work fine. I deleted the layers and generated a new code but it is unable to open. I don’t believe it is a creator issue as well. I created a different map and a private code for that worked perfectly fine
