For anyone coming across this, the solution is here:

> [@Engine(5.5.0) taking up more than 150GB (Linux)](https://forums.unrealengine.com/t/engine-5-5-0-taking-up-more-than-150gb-linux/2148381/5):

> While 5.4 used to work fine, and 5.5 Preview 1. Now with the latest code from the 5.5 branch, I also get those errors. It seems somehow UBT enables the Intel SPMD compiler and that’s why it fails: #if INTEL\_ISPC #include “NiagaraDataInterfaceVectorField.ispc.generated.h” #endif 0\>GeometryCollectionComponent.cpp(94,10): Error : ‘GeometryCollectionComponent.ispc.generated.h’ file not found 0\> 94 | #include “GeometryCollectionComponent.ispc.generated.h” 0\> | ^ ~~~~~~~~~~~~~~~~~~ …

Just add the following lines to your Game and Editor’s .Target.cs and rebuild:

```
   // Disable Intel Implicit SPMD Program Compiler forced by UE 5.5 on Linux.
    bCompileISPC = false;

```
