Hello Jacoby Stéphane,
(Just to clarify — my name is not “재현 방법” 
That text means “Reproduction Steps” in Korean, and it seems the support system automatically used that field as my display name. My actual name is hojong)
Thank you for your response.
I have one additional question:
In UE 5.7.0, how can I disable Metal libraries?
I could not find an option for disabling Metal entirely in Project Settings → Platforms → iOS.
I only see the Metal version selection options, but not a way to disable Metal library generation.
Could you please guide me on how to properly disable Metal in this version?
Thank you again for your help.
