Description and steps
I was modeling a chest.
Every piece of the chest is a separate object.
I've UV unwrapped every object individually.
On the Layout tab- I select all objects. Then enter object mode. Select everything with the "A" key.
On the UV Editing tab - Select everything again. On UV, select "Average Islands". Then select "Pack Islands".
Blender imediatly closes after following the previous steps.
