Character disappearing in standalone mode

I am having an issue with my player character starting off in mid air as if in the first person perspective then the main player character will appear in place a few moments later on the ground then latter disappearing again later while in standalone mode in UE5.02. When I move across the landscape, the character will disappear, and the camera will become unresponsive as soon as I hit a different boundry while using Worldpartition. I also noticed that before the character disappears, I will run across the main player character where it was placed before the start but can be seen as a ball. I can move the character to a different section of the map, and again in standalone mode the same thing will happen. Any ideas on how to solve this?
