Hello,
I was using Audacity 2.2.1 yesterday on Windows 10, when the interface suddenly became unclickable: elements like track balance slider still responded somewhat to a hover, but any click caused a Windows click-or-action-is-not-possible sound. Please see attached debugreport created by Audacity.
Luckily Audacity had just made a back-up so I could continue where I left off
