BTT not showing up on MacBook Pro running OS Mojave 1.14.6.

Hello, I recently got BTT and it does not show up despite having been given access. I have followed the "remove access and re-adding it" procedure, but each time I do my computer freezes (the mouse works, but I can't click on anything) so I have to restart. When I reboot, BTT shows up in the accessibility list but unchecked and when I check it again, it doesn't do anything, so I remove it again by pressing the "-", then it crashes... cue repeating issue. I have a MacBook Pro 2016 and I have 1.14.6 OS Mojave.

If additional info is needed, please be descriptive of how I can obtain as I'm not particularly well versed in fixing bugs with my laptop. Thank you!
