Looks like the build process ran out of memory, or hit memory fragmentation issues. If there’s anything you can do to reduce Unity’s memory footprint during building (for example, smaller, simpler, or fewer assets), you might try that.

Alternatively, how much memory does your machine have available at build time? If you’re concerned that might be an issue, you could try closing other programs or upgrading your machine’s available RAM.
