Crash when using GPU Lightmass after updating project to 5.3.0

Hi @Wheatttttt ,
You configuration will allow you to use

Epic's GPUlightmass

If anyone doesn’t want to go through the hassle of building their own copy of 5.3 from source with the 5.4 fixes for GPULM, I compiled a binary installed build, which is a 10GB download and 25GB on disk. I’d be happy to share the link with anyone that needs it.
