Building Lighting Stuck at 0% and failing

I have a landscape level with many trees, flowers and bushes foliage assets and when i try to build lighting by clicking on Build Menu… Build lighting only… It’s stuck at 0% for a while and failing to build with some error message logs. I have light mass volume and post process volume placed around the scene. I’m an absolute beginner and any help would be much appreciated. Thank you

How much RAM do you have? Lots of foliage is going to cause a high amount of memory use, and depending on what you’re doing it might not be a good idea to use baked lighting for that reason.
