**Description** Hi, there. I’ve downloaded the latest version of ZoomVideoSDK 1.3.3. When I’m trying to get one of Zoom’s callbacks I tend to get an error instead: “Thread 1: EXC\_BAD\_ACCESS (code=1, address=0x3da7ad330)” at main This error is 100% reproducible when one of the users leaves session. I don’t get onUserLeave callback, but I do get an error. As a workaround I reverted SDK to the previous version and it works fine. **Which iOS Video SDK version?** 1.3.3. The previous version (1.3.2) is stable **Smartphone:** - Device: both iPhone 12 and Xcode Simulator - OS: iOS 15.5 ![bad_access](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/c/f/cf6c77e3e9d836e1a202fba3813025160680752d.png) ---

I am seeing the same exact crash. happening in 1.3.3, not happening on 1.3.0, 1.3.1, 1.3.2. ---

Just tested with v1.4.0 - same crash. ```auto EXC_BAD_ACCESS addObject: > getCmmUserByUserId: > getUserById: > numberWithUnsignedInt: > removeUser: > Attempted to dereference garbage pointer 0x165e15957400. ``` **To Reproduce** - make 3 users join a session - trigger a crash on user 1 (call `fatalError()` for example - or stop execution in Xcode) - the SDK callbacks are not called for user 1 - so user 2 in 3 are still seeing user 1 being part of the session - after ~30sec both user 2 and 3 will experience the crash above - the SDK timed out user 1 and tries to remove it casing the crash to happen ---

@rokgregoric Thank you for reporting this issue. It seems your app crashed when you receive the error of Errors\_Session\_Disconncting(2008), right? We test with SDK demo app, can’t reproduce the issue of crash, it must have some different operation between your code and SDK Demo code. Would you mind to give us a call stack of this crash issue or some sample code? Thanks ---

@jackie.chen no … the app is not crashing on 2008 … this happens randomly when accessing the user object. here is a crash stack trace: ```nohighlight Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: BUS_NOOP at 0x0000000f013cb770 Crashed Thread: 0 Application Specific Information: addObject: > getCmmUserByUserId: > getUserById: > numberWithUnsignedInt: > removeUser: > XTUM > Attempted to dereference garbage pointer 0xf013cb770.

@rokgregoric Sorry, one more information needed. Which SDK version was used of this crash call stack? And, please give us the full crash call stack, that will be useful for tracking. ---

Hi @rokgregoric and @veerlorden , I am waiting for your crash call stacks and SDK version for debug this issue. Would you kindle send us this two informations. Thanks. ---

v1.3.3 was used used … but v1.4.0 produces the same crash. The crash stack is above. ---

Hi @rokgregoric , The call stack you paste is not enough to analyzing. If the crash happened when you developing, please input the command “bt” and “image all” and copy the output to us. If the crash not happened in developing. Please check the device log by Xcode. There have the full crash call stack. Thanks again for report this issue. ---

I ran `bt all` and `image list`. Here is the log [WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free](https://we.tl/t-J5K3ThnaYc) Hope this is OK … LMK if you need anything else. ---

I replicated this simply by running the app from Xcode and after the session has started, re-run the same app without quitting it - Xcode kills it. When the app restart there is a fantom/zombie user (the old one) still in the session. After around 30sec - when the zombie user times out - it gets disconnected - causing the crash to occur. ---

Hi @rokgregoric , After Engineer analyzing, the SDK you used is 1.3.3.1231 and the SDK is for x86\_64 simulator. Would you please have a try with device SDK of 1.3.3.1231？ And get the “bt” and “image list” output for us. I tried the way you mention above, but still can’t reproduce, even I used the simulator SDK same as you. Thanks a lot. ---

Hi @rokgregoric , Sorry to bothering you again. We need the log from you app launched to crash happened. You can normally reproduce the issue. After crash, you can get the log from Xcode → window → devices and simulators → select device → download containers → and zip the “tmp” folder in the sandbox → send the zip file to us. Thanks again 🙂 ---

here you go [WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free](https://we.tl/t-xsEU9rwG7J) I updated the initParams so you have multiple logs inside - I’ve also added crash reports from the device itself. This time it was on iOS 15.7 ---
