It’s likely a mistake. Call the airline and they should be able to correct it, and offer you a new itinerary that is actually possible.
Standard procedure when an airline changes their schedule is that they will update your whole itinerary, rebooking following flights as needed, to get you to your final destination. That didn’t happen correctly in this case, which is probably an error on their part. It isn’t normal.
(In some cases, e.g. if the airline is going to stop serving a city entirely, they might unilaterally cancel your reservation without offering you a new itinerary, and refund your money. But that doesn’t seem to be the case here.)
If the new (possible) itinerary doesn’t fit your travel plans, you should have the option to cancel the whole booking and get a full refund. Since this flight goes to the EU, it’s possible you might be eligible for additional compensation as well; maybe someone more familiar with EU rules can discuss this.
