Can't open Better Touch Tool anymore

Hello,
I've been using BTT for years and now when I try to open it, it immediately closes.
I have restarted my Macbook Pro 2012 (Mojave) but it still doesn't work..

Part of the log :
65716752.923446|LAUNCH|DIDLaunch START|
1565716752.937254|SYS|Running on macOS: 10.14.5|
1565716752.937313|SYS|BTT Version: 3.172|
1565716752.937384|SYS|Device: MacBookPro9,2|

The end of the log says something about the licence but what can I do ??

Oh solved it with another topic : i had to uncheck then recheck BTT from Prefs > Privacy > Accessibility. Now seems to be working as expected.
Sorry for this bug report ..
