Swiss airline has laid off a lot of staff during COVID. Now they lack staff and cancel lots of flights.

I have a flight to Copenhagen at the end of the month. I have already paid for the hotel (before COVID) and it is non-refundable.

What do I do if the flight to Copenhagen is cancelled? Then I can not be in the non-refundable hotel and lose a lot of money.

Update: Conversation with Swiss chat bot.
