BTT v3.506 no longer auto-launching at boot

Hi there. I've been using BTT since around Nov 2019 and it has always auto-launched when I boot my MacBook Pro 16" (running Catalina 10.15.7). However, this has stopped in the last week or so i.e. BTT is no longer auto-launching despite this config option being enabled AND BTT being listed as a Login Item in System Preferences/Users & Groups/User/Login Items.

I've toggled the auto-launch option in BTT many items and have downloaded and replaced the BTT success.

Is there anything else I can try?


EDIT: I've managed to get BTT auto-launching again by resetting the PRAM.
