BTT Custom Touchbar isn't visible


I've had BTT for about 2 years now and one day, a couple months ago, my custom touchbar just doesn't show up (I've been too busy and forgot about it until now). I tried setting up a keyboard shortcut to Show the BTT Touchbar, but nothing happens besides the "esc" key quickly blinking. I'm not quite sure what to do about this. Please send help

Thank you
