Summary
This has been happening to all of my bigger maps. I randomly get this cook error, and it feels similar to the memory cook issue where we have no idea what’s causing it or how to fix it.
The only workaround seems to be removing almost all assets and redoing a ton of hard work, just for the issue to eventually come back again.

Additional Notes
This issue, along with the memory cook problem, has been ongoing for so long that it’s now approaching a full year without any clear resolution. Despite multiple updates, it still hasn’t been properly addressed, and it continues to impact large projects in a major way.
For additional context, this started around the Star Wars season, and ever since then creators working on bigger maps have been running into the same problems with no reliable fix.
