Build succesful but error when running. Assertion failed: LODInfo.OverrideVertexColors == nullptr

Hi, I’m working on a project which runs fine in editor and builds fine but when running the .exe we get the following error message and the .exe closes.

While the error pops up. I can see the game rendering properly behind it and vertexcolor working just fine.

I’m only using VertexColor as a simple basecolor input in material. That material is applied to the basic plane which is a component in a blueprint which sets its color using the “Paint Vertices Single Color” node.

I’m at a bit of a loss here, so any help is much appreciated!
