Now that you mentioned it, the worst thing you could do if your hardware wallet breaks/stops working is to start panicking. Some people do that. Omg, my HW isn't working, what do I do? I must hurry and see if my crypto is still safe. And that's when mistakes happen. If they don't have a second hardware wallet, they will enter their seed into a hot wallet just to see if everything is ok. By doing that, they just downgraded the security of their coins and you can't get that back.

Physical issues with the signing device don't affect your crypto unless you leaked your keys as well. If your primary HW is no longer working, remain calm, don't enter your seed anywhere, and wait for the replacement to arrive (assuming you ordered a second unit).
