Hi @Elagin - can you please mention what client library you are using and on what iOS device? What engine have you used to build your game?

3

Hi! Thank you for reply. We are using Unreal engine and Unreal sdk. So we find out that Unreal sdk use c++ library. Firstly we used prebuilded library and get this error, then we build it manually and get the same error

@mofirouz we test it on Iphone XR with ios 14 onboard

Thanks. Do you have an idea of where in your code this happens? Eg are you init the client or calling a function or connecting to the server?

Do you have a stacktrace that shows more details?

@mofirouz it happens when we call createDefaultClient in our GameInstance Init function, so we get crash on launch

Thanks @Elagin - can you please create a minimal example demonstrating the issue, and open an issue in the tracker here (with the example):
