**Description**  
We are using Zoom Meeting SDK in our WPF product. During ending of a meeting we sometimes encounter “Attempted to Read or Write to protected memory” exception and this causes an app crash. I am unable to add ZoomSDK logs to this ticket.

**Which Windows Meeting SDK version?**  
5.17.10

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Start a meeting with multiple users
2. End the meeting from user interface

There is no consistent way to trigger the crash. It happens randomly.

Hi @ege.apak , we have not seen this error before, but upon further research, it seems this error appears “when the application tries to read or write into the memory using a pointer that has a bad value” and can [be difficult to isolate](https://supportcenter.devexpress.com/ticket/details/q431770/attempted-to-read-or-write-protected-memory).
