Mac Studio + Ventura = Airdrop not working

Hi guys, I've an M2 Max Mac Studio since a few weeks with the last version of Ventura 13.5.1 (but previous updates had the same problem too) and I'm having big problems with Airdrop.

Of course I've configured it correctly (everyone can see me, etc.) and, when MacOS has a fresh start (= just rebooted), Airdrop works like a charm. After some hour, I'm not sure but maybe with some computer sleep involved (like during night), the Mac can't see anymore other Apple devices, and they can't see the Mac, despite the fact they see each other correctly).

My only solution is to restart the Mac and Airdrop starts working again.

Since this machine is accessed by more than an user, it's a problem to restart it every time. Is there a way to fix the problem forever? It's ok even a procedure that involves killing and restarting some process(es) (restarting Finder doesn't solve the problem).

Thanks
