This, apparently, is a bug in Update 2, which is reported here , and I hope it will get enough speed for MS to take action sooner rather than later.
In the meantime, you can disable everything from the debug menu, rather than stopping the debugging process.

If you want to disconnect everything on your toolbar, you can do this through the "Tools", "Customize" menus and under the commands, select the "Toolbar" radio amateur and select "Debug" from the drop-down list. Add a command, select "Debug" and select the "Detach All" command.

which then gives you this
