I found a reason to the crash and a workaround
Reason:
I was using some assets from the Old Brick House pack and I .gitignore thirdparty packs. I copy used assets to my project folder so I only version the used assets to reduce git size. I’ve found that 2 assets were using materials still in the pack folder and deleting them from the map made the Build go without crash. I downloaded again the pack and replaced the old folder with the new but the crash would still happens if the assets were points to the pack, so I found a work around and a theory.
Workaround:
Re-Download (or not) and copy/paste used assets from pack folders including any material or texture into a new folder.
Theory:
Maybe the pack that isn’t 5.0 ready need to be rebuilded by the owner and copy/pasting the assets converts them to 5.0 ready.
