Occasionally keep command key pressed

Describe the bug
The operating system will behave as though the CMD button is pressed.
Symptoms, navigating a webpage means every link is opened in a new tab, or pressing the letter 't' automatically opens a new tab. Pressing 'tab' brings up the application switcher. etc...

Quitting / restarting BTT solves the problem. I cannot tell what triggers the problem to start with though, but it seems to occur every few hours of use.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
not one input device specifically, but each device is affected in the same manner as though I were holding the 'CMD' button.

Screenshots

I can try to provide a video if you think that would help, but it's a pretty straightforward bug.
