Landscape completely disappears after pressing play???

I imported a landscape from Gaea to Unreal 5.1 and I am having a problem with my landscape disappearing whenever I try to press the play icon and play my game. After pressing it, it literally looks like there’s a black void on the lower part of my screen.

I tried to look everywhere for a solution (it looks like there have been quite a few people who have had this problem. I tried pressing alt+L, pressing G, adding a material to the landscape, re-adding the player start object, etc. I have no idea how to fix this.

Has anyone else ran into this problem before???

Here’s a link to a video that better shows the problem, and down below is an image that shows it too (the bottom part of the viewport where it’s black is where my landscape should be).

Also, here is a zip file to the actual project.

Hi @objectedbear431 I had a look at your project and it appears that your landscape is really far below the grid line. When this happens the player disappears it’s the same principle if you jump off a ledge into the void.

If you notice there is a grid where the lighting and other stuff is, if you raise your landscape and the player start, up to it or even above the grid then you will notice your player no longer disappears.

Play around, bringing it higher and higher until it works.
