Delayed trackpad gestures at login (Catalina)

Sometimes, when I switch on my MBP 16" and login to my user, configured trackpad gestures need a couple of minutes or more to work.
BTT is correctly working in background, in fact keyboard shortcuts, to give an example, work immediately at startup.

Unfortunately I'm not able to reproduce this weird behavior every time; sometimes trackpad gestures are immediately active, sometimes not.

Could you please help me?
Thank you very much.
