Package Error : FMemoryWriter does not support data larger than 2GB. Archive name: None.

When I pack, something goes wrong. but i don’t know where should be fixed.

Here’s my guess. There are two maps in my project. the second map might be too big. because I needed about 90s to load I think the second map is the point of issue.
