output_log SpacialMappingRenderer errors, despite not using it?

Hey,

So I've been working on a 2D space game. I'm trying to fix a few bugs after building and while I'm looking at the log, it's filled with errors to do with a SpacialMappingRenderer. This isn't something I've ever used and I'm not sure what it does, if there's a way to fix these bugs etc or if I should just ignore them as it's not affecting anything game-side (I don't think).

Here's my output log:

Also, I'm noticing the SHIP error that's coming up where a reference/cast is missing. I'm not getting that error in Editor and I'm not getting any visual issues in the build that I can see.

Firstly, anybody know what the SpacialMappingRenderer deal is and why it'd be coming up and if there's a way to fix?

Secondly, how I can find out which SHIP reference may be broken and why? As it's all working before I build.

Thanks in advance :)
