I’ve developed a game in Unreal Engine 5 and packaged it for Android. The app installs successfully on my device (Nokia X20, running Android 14), but it crashes shortly after starting. The crash occurs consistently, and I’m seeing the following errors in the adb logcat output:
D/UE : [2025.07.03-23.27.53:292][ 0]LogProperty: Warning: Serialized Class /Script/Engine.CharacterMovementComponent for a property of Class /Script/Engine.SkeletalMeshComponent. Reference will be nullptred.

Could anyone help me?
I have no idea what’s the problem (except it’s the Kallari_Template blueprint character).
