Unity crashes on baking scene with several unity trees

My scene doesn’t crash if I take off the unity trees, and still works fine if I have one tree present in the scene, but as soon as two or more are enabled, it crashed while exporting to beast ( on the light probe phase.)
Any clue as to what is happening?

Find the tree prefab that causes the crash, and give it a new seed!

I had this problem with unity crashing at the light probe phase when exporting to beast. To me, it wasn’t related to the number of trees in the scene, so I tried baking each tree prefab instance individually. Eventually I found that one particular prefab instance would crash each time I baked it, so I changed that prefab’s tree seed. Note that the crash happened to all instances of that particular prefab. After that baking worked just fine.
