Keep encountering the same crash at seemingly random points, I’ve looked up this error and tried just about every solution I can find, including massively optimising my lighting. If anyone has any idea how to prevent this crash, I’d be incredibly grateful for any leads. Thanks for reading, thank you
Hey, did you find a solution for this?
Greetings @Manula96
I’m late to the party. But, I’d be happy to take a look. Do you have a full crash log of the error you’re seeing? I’ll monitor the thread.

Welcome to the Unreal Engine Forum! Take a peek at this thread and see if this is the same issue(If so, check the solution found there) Crash in FMallocBinned2::MallocExternal on Win64
Hey, i’m getting basically the same error as the original poster, and I went to the thread you linked but have no clue what any of it means, any ideas for what I can do? Also I have 64gb of RAM but I’m not sure how to take advantage of that in this situation
