Hi,

I’m developing with Zoom SDK and I realized that app is crashing not always on same line but on same “CCustomizeUIVideoMgr::ReSubscribeNormalUser()” function when last user using a webcam leaves the meeting and SDK is playing Gallery view and using Customized UI.

Error is: “sdk\_demo\_v2.exe has triggered a breakpoint.” and it points to ntdll.dll.

Tested versions: 5.7.1.644 and 5.7.6.1079.  
Tested on few Windows 10 and Windows Server 2019

Hey @Pablo.Moreno,

Thanks for using the dev forum!

Can you reproduce the crash one more time and send me the SDK logs and dump files from that instance? You have to set [enableGenerateDump](https://marketplacefront.zoom.us/sdk/meeting/windows/structtag_init_param.html#a7303a4d28fb1b3c6a2a4a2582792be6b) and [enableLogByDefault](https://marketplacefront.zoom.us/sdk/meeting/windows/structtag_init_param.html#a9705b3c9e1bfe7d617c5e55785939f83) to true in your initParams and then the logs can be found in %appData%/roaming/zoomSDK.

Thanks!  
Michael

Hi Michael,

We do have the log file ready but I am not able to upload the file to this forum, since only jpg/png files are allowed.

Is there a url/email where I can upload the log file ?

Thanks,

-Deepankar
