Could someone point me in the right direction as to what is wrong? It crashes in a certain place during gameplay but I cannot understand why.
I’m using Blueprint only and have some plugins in my project, it has been converted from 5.3 to 5.4

Hello,
It’s been more than a month since you post that, but I am experiencing the same issue in UE 5.4.2. I found out that in my case it come from the metahuman hair (because when I remove it, it does not crash anymore). But I have not found any fix to this issue yet … Let me know if you achieve to fix it !

Same for me about the hair, and only in some unknown circumstances. For now all my metahumans are balled…
