On macOS, StartMacSandbox runs before CrashReporter::SetRemoteExceptionHandler in XRE_InitChildProcess. The crash reporter triggers NS_LogCtor which lazily calls InitTraceLog, which tries to fopen XPCOM_MEM_BLOAT_LOG and related env var paths after the sandbox has locked down file writes, causing a MOZ_ASSERT. MOZ_LOG_FILE doesn't hit this because LogModuleManager opens the file during LogModule::Init, before the sandbox. Mirror that pattern: call nsTraceRefcnt::EarlyInit() right after LogModule::Init so the XPCOM log files are opened while the process still has full file access.
