What could this error code be in reference to?

I make community mod maps for a game and had to update to a different UE engine. Went from 4.20 to 4.25.

Problem is when I try and open up my level, the level is loaded for a few seconds before it crashes, giving me this error code.

Error code: "Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:E:\Epic\UE_4.25-plus\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 674] Array index out of bounds: -1222485392 from an array of size 56"
Anyone know what this is? Something to do with RAM I presume? Do I have too little memory? Also, is this a map/file issue or a my PC issue?
