Map making crash: "NANITE_MAX_INSTANCES -- are there too many particles?!"

I’m relatively new to modding/Ue5 so forgive me if anything obvious to you is completely missed by me! I’m working on an ASA map and I’m pretty early in it’s progression. Only about 10% of it has foliage and painted terrain.

My work has come to a sudden halt once this particular crash began hitting me nonstop near specifically painted terrain. Specifically anything not sand (grass/fertility/forest floor)

I have tested opening the project and going into a very distant corner where there are no objects near and painted a chunk with forest floor and fertility and bam, it happens again. (The crash wont trigger unless I get in render distance for the grass and stuff to begin popping up)

I’m basically just unsure what this means or why just having basic terrain down is doing this? I’m hoping I’m missing something obvious here but no one has had answers for me in discord’s/elsewhere.

The entire crash log:
"Fatal error: [File:W:\Repos\ASA_ModKit\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 954]

Pretty desperate for any help since this project has been a long one and I really hope to overcome it
