BTT not working on Cantalia 10.15.3

Hello - I have been using BTT for several months now (using only the Touch Bar features) without any issues. In recent weeks however, I have had to keep removing and re-adding BTT in the Accessibility part of the Privacy settings. This worked until today.

I have tried the Terminal command to reset too, however, it just freezes my computer and when I force a restart it's still not working,

Also I tried uninstalling and re-installing.

Any help would be appreciated please.
