Hi redmage,
Looking at your log you have the couple of material issues that you mention along with there is one about the LOBBY_Chandelier001 being more than 65535 k vertices. This will not work for mobile and exceeds the maximum number of vertices a single asset can have.
You can try fixing that and see if you’re still getting the crash.
Some additional things to test and see if you’re still getting the crash:
- Open a new default level and add a few basic assets to see if you can launch with this level.
- Try a blank project with a default scene and a few assets.
- If you’re set a splash screen try removing that and see if you get the same crash on the device.
- Try testing your build with 4.12 Preview 5 that is available on the Epic Games Launcher. This may have already been fixed, but can help see if the issue is already resolved.
As for the second log that seems to indicate that it ran out of memory with 33mb left to allocate when it ran out.
