BTT seems to be causing temporary hang

If I walk away from my 2018 Macbook Pro 13" running latest version of Catalina (10.15.7) and latest version of BTT 3.4045, and then come back in a few minutes (I have a 5 minute energy saver toggle) the screen comes back but is frozen. Cursor does not move. Hitting the virtual touchbar esc key does seemingly nothing. Then about 10 seconds later it comes back to life. I don't have Dropbox Sync enabled. Thoughts?
