Microsoft developers are currently investigating a bug that causes the Copilot AI assistant to crash if you run multiple Office apps simultaneously. For example, if you open Excel, one instance of WebView2 starts—but if you also open Word, the system tries to launch a second instance of WebView2.
According to a Microsoft support page, since Copilot is based on WebView2, the result is that the AI assistant crashes and a dialog box appears prompting you to “restart all Office applications and try again.”
“Multiple customers have reported issues with Office features that rely on WebView2, notably Copilot, Share, and Room Finder,” Microsoft writes in the support document (spotted by BleepingComputer). “The most impactful symptom is the failure of the Copilot pane to launch when multiple Office applications are open simultaneously.”
However, given the cause of the problem, restarting your Office apps isn’t enough for a solution. Until a fix is available, you should only run one Office app at a time if you’re going to use Copilot.
