**Description** Our Zoom SDK app crashes randomly with no indication as to why. (I’ve created [this topic](https://devforum.zoom.us/t/faulting-module-name-zvideoui-dll-version-5-5/53824/13) recently, but it isn’t the same crash - this crash does not register in windows’ EventViewer, but does send data to logs/dumps) **Which Desktop Meeting SDK version?** 5.5.12511.0422 **Device:** Windows server 2016 Adding logs/dumps here - see the 3 folders ending in 4012 (those were created at the time of the crash 14:00 ~ 14:17): [https://drive.google.com/file/d/1UjCCh7VGAikXYNVVrdUhqr3ikU5COsPx/view?usp=sharing](https://drive.google.com/file/d/1UjCCh7VGAikXYNVVrdUhqr3ikU5COsPx/view?usp=sharing) @Michael_Condon can you assist? 🙂 ---

Hey @oren.nahum, Thanks for using the dev forum! I know you already updated to investigate the other crash you mentioned. Unfortunately, we would need to see the crash happen in the latest version to investigate. Can you let me know if this ends up happening in the latest version? Thanks! Michael ---

Sure, Can I send you in private? or email? I’ve sent an email with the steps to [zoomdeveloper@discoursemail.com](mailto:zoomdeveloper@discoursemail.com), hopefully they can forward it to you (I’ve asked). ---

Hey @oren.nahum, It looks like there are SDK calls being run on child threads in your application. Can you move all of your SDK calls to the main thread? The SDK must run on the main thread. Thanks! Michael ---
