I’m trying to build my project using Unreal Engine 5.4 for iOS. I use SocketIO to connect to the backend. The plugin SocketIOClient version 2.8.0, is used for this.
When trying to connect to the socket, a crash occurs. This only happens on iOS, only in Distribution builds, and only on Unreal 5.4. There are no problems on Unreal 5.2. Callstack:

EOF
The callstack may be slightly different, but the problem is always when allocating or deallocating memory. I suspect that this may be a race condition and is related to some peculiarities of working with memory on iOS. There are also several similar issues in the plugin repository, for example this one.
I tried using other versions of plugin, other versions of xcode, tried to build socket io using both c++20 and c++17, nothing helps. Does anyone know what can be done about this?
