Cook一个WC地图，这个地图里面有个世界分区地图的关卡实例，然后Cook关卡实例过程中，触发了这个崩溃，是偶现的，后续发现可以正常Cook结束，想问问既然有这个断言是否有相关排查手段

您好，内部jira上有类似的问题，但是还处于未解决的状态。

排查的话，可以先加上命令-LogCmds=“LogWorld Verbose, LogCookGenerationHelper Verbose, LogLevelInstance Verbose, LogWorldPartition Verbose” 获取更多log

然后添加一些额外信息

void FWorldCookPackageSplitter::OnWorldCleanup(UWorld* InWorld, bool bSessionEnded, bool bCleanupResources)
{
      if (InWorld == ReferencedWorld)
      {
              // Debug: identify who is cleaning up the world referenced by the splitter
              UWorld* OwningWorld = (InWorld && InWorld->PersistentLevel) ? InWorld->PersistentLevel->OwningWorld.Get(
              UE_LOGF(LogWorldPartition, Error, "[Cook][Debug] Splitter world %ls cleaned up. OwningWorld=%ls bSessionbCleanupResources=%d IsInitialized=%d",
                      *GetFullNameSafe(InWorld), *GetFullNameSafe(OwningWorld), bSessionEnded, bCleanupResources, InWorld->IsInitialized());
              FDebug::DumpStackTraceToLog(ELogVerbosity::Error);
      }
      ensureAlwaysMsgf(InWorld != ReferencedWorld, TEXT("[Cook] %s is being cleaned up while still referenced by a pacsplitter."), *GetFullNameSafe(InWorld));
}

再在 ReportGenerationManifest 和 Teardown 里各加一行日志，打印 ReferencedWorld 的名字和时间点。这样日志里就能拼出完整的"splitter 持有期间，被谁清理"的时间线。

如果能做一个复现工程发给我们那就最好了

这个不是稳定复现的，我先看看加上日志方便排查
