If you are having issues with the dashboard crashing, you can check the dashboard logs to find the cause. The WHS dashboard log file is located at "C:\ProgramData\Microsoft\Windows Server\Logs\" and is called "Dashboard.log" (note there may be more than one dashboard log file, in this instance, please send all "DashboardX.log" files).
If you believe the Drive Bender addin is responsible, create a support ticket with the details and the dashboard logs.
You can also temporally disable the addin, see this article.
