Visual Studio 2019 Community 16.8.4 crashes when drag and drop Tab

Question

Visual Studio 2019 Community 16.8.4 crashes when drag and drop Document Tab.

I have re-installed VS 2019 Community and it does not fix the problem. I have been using 2019 Community for a year now with no problem. Not sure if it is related to 16.8.4 or not.

Has anyone else had this problem? If so have you figured out how to fix it?

Answer 1

[Workaround]

Edit %InstallRoot%\Common7\IDE\devenv.exe.config and %LocalAppData%\Microsoft\VisualStudio\16.0_xxx\devenv.exe.config and append the following text to the AppContextSwitchOverrides element’s value attribute:

;Switch.System.Windows.Interop.MouseInput.OptOutOfMoveToChromedWindowFix=true;Switch.System.Windows.Interop.MouseInput.DoNotOptOutOfMoveToChromedWindowFix=true

After restarting VS, you should be able to drag your VS windows around without crashing. https://developercommunity2.visualstudio.com/t/Unexpected-VS-crash-when-docking-or-spli/1323017#T-N1330689
