Resolve SSMS Crash when opening Database Diagram?

Kevin Locke 21 Reputation points

Microsoft SQL Server Management Studio v18.10 (15.0.18390.0) crashed while editing a database diagram. Since the crash, attempting to open the diagram also causes SSMS to crash. When running with ssms.exe -log SsmsLog.xml, the last entry in SsmsLog.xml is:

     <time>2021/11/03 16:10:33.131</time>  
     <description>Begin package load [Scc Display Information]</description>  

It also logs Event ID 1026 to the Event Log with the data:

Application: Ssms.exe  
Framework Version: v4.0.30319

   at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr, Int32, IntPtr, IntPtr)  

Followed by Event ID 1000 with the data:

Faulting application name: Ssms.exe, version: 2019.150.18390.0, time stamp: 0x615720fe  
Faulting module name: KERNELBASE.dll, version: 10.0.19041.1288, time stamp: 0x3e55bd0b

Faulting application start time: 0x01d7d0cd40c55427  
Faulting application path: C:\Program Files (x86)\Microsoft SQL Server Management Studio 18\Common7\IDE\Ssms.exe  
Faulting module path: C:\Windows\System32\KERNELBASE.dll  
Report Id: c0db3f3e-fcfc-47b6-8f7c-7c69895fca8c  
Faulting package full name:   
Faulting package-relative application ID:   

Any suggestions for how to further investigate or work around the issue? Or to avoid it in the future? Or a better place to report such issues?

    I suspect that that particular diagram is lost. But you can report the issue on If the database is small, try to attach a backup to the bug report so that Microsoft has something to work from. (The feedback site is a new one, and I have not explored it myself yet, so I don't know what you can attach.)

    There were plenty of reports about diagrams causing crashes with earlier versions of SSMS 18, but I have not seen them for a while, so I guess that the general problems have been sorted out. I don't use diagrams myself.
