Cannot add new widgets or buttons to Touch Bar

Cannot add any new buttons (add new group doesn't work either) to Touch Bar, add new button engages, but doesn't trigger a new preset. Afflicts Touch Bar and keyboard

2017 mbp 15, up to date everything, just stopped working last night when clicking to add new.

If anyone is having this problem, I finally found my solution was to delete the app, then head to libraries and delete all cached data and everything that had to do with better touch tool. Then I reinstalled the app, and it worked again
