BTT self disabling

I have just migrated to a new iMac. Now BTT sits in the menu bar greyed out. It reports itself to be disabled but when I restart it, BTT greys out after a second. It was fine on OS 12.8 but now on 14.3 it is doing this. I am sure I had the problem a while ago and it was solved by a suggestion from forum admin but I can't find it now. I have given BTT full disk access in Security.

Thanks for your help. J.

Sussed it!
In the dropdown from the icon I needed to open the link enable BTT for all apps and select the line again. Working!!
