GAEA heightmaps not importing to UE 5?

I need an adult X_X

I am trying to use GAEA (ver 1.3.0.13 community edition) to create a heightmap for my landscape. However, no matter what I do I get an error when attempting to import.

So I decided to get access to a pre-generated map and upload it. I know this map works because I’ve seen the final project in which it is used. However, when I try to import it into UE 5.0.3, I get that same blasted error!

Can anyone PLEASE help me to fix this? I’ve tried using World Machine but it isn’t as intuitive as Gaea.

Thank you in advance.
