Info: Microsoft .NET September 2022 Update Crash

DriveWorks is aware of an issue, where opening certain stages in DriveWorks Solo will crash immediately with UpdateExtent shown in the title of the crash dialog.

This issue is related to a recent Microsoft .NET update which is rolling out to some customers.

DriveWorks is still investigating the root cause of this issue to determine an appropriate course of action, however, in the meantime, see the workarounds below.

Microsoft Update Details

The Microsoft .NET Updates that are currently known to trigger this crash are as follows.

If you are experiencing an UpdateExtent crash, you can check your Windows Update history to determine if one of the following updates is installed.

Workaround

Workaround 1: Suppress the new behavior caused by the update (Preferred)

Microsoft have provided the capability to disable the new behavior in this update, but it requires a registry change.

Manually Updating the Registry

This registry change can be made manually by using the registry editor to create the following value:

Note that neither the AppContext key, nor the Switch.System.Windows.Controls.VirtualizingStackPanel.OptOutOfCollectionChangeFix value are likely to already exist.

If you need to create the AppContext key then you can do so by right clicking on .NETFramework in the tree on the left of the registry editor.

To create the Switch.System.Windows.Controls.VirtualizingStackPanel.OptOutOfCollectionChangeFix value, with the AppContext key selected in the tree, right click in the values area on the right hand side, and choose New -> String Value.

Automatically Updating the Registry

There are a number of possible options for automatically updating the Windows Registry.

The first is to create a file containing the change, and double click it to apply the changes. In addition, your IT organization might be able to automate this change centrally.

To apply the first option, create a text file with the following contents:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\AppContext]
"Switch.System.Windows.Controls.VirtualizingStackPanel.OptOutOfCollectionChangeFix"="True"

Name this file with a ".reg" extension:

For example, PreventCrash.reg

Once created, double click the file to run.

The registry editor will ask whether you really want to apply the change.

The key shown in the image below will be created:

Workaround 2: Uninstall the Microsoft.NET update

It is possible to remove the relevant update from the above table from your operating system, which will resolve the issue.

For more information on how to do this for your operating system, please consult the Microsoft documentation Windows Update: FAQ (microsoft.com).
