Hi @utku.erturk ,  
Did you build you app with embed ‘ MobileRTCResources.bundle’?  
If the crash still exist after you include the bundle file, please send us the crash log.  
With type “bt all; image list” in the lldb console when the crash issued again. And copy the output text to us.  
Thanks

Hi @jackie.chen ,

Sorry for late response. I didn’t see the notificaion email.

When I type _bt all; image list_ it gives error.

(lldb) bt all;image list  
error: bt [| all]

You can find the logs below with **bt** command

Hi, @jackie.chen

When I debug the app, I discovered another log. This log printed when I clicked the … button.

```auto

)}'. This will be disallowed in the future.
data parameter is nil
(null)

```

As you can see there is a **ZMRecentEmojiMeta** on the list.

And the logs says **MobileRTC`\_\_\_lldb\_unnamed\_symbol**

Could the error be related to emojis? The application receives an error in 3 cases.

1- Click chat button  
2- Click one of chat emojis on this screen  
3- Click the … button near the emojis

Hi @utku.erturk ,  
Does your app include the MobileRTCResources.bundle for resource load?

Hi, yes it was attached but the MobileRTC Resources.bundle version is outdated.

Once we added the one for 5.12 the issue was resolved.

Thank you for your help.
