Pull out the switch and make sure everything is still wired correctly. Use a multimeter with the switch disconnected to see if it is working correctly.

If no one messed with the wiring, how would it suddenly become incorrect?

The problem isn't "I tried to swap out a switch, and now nothing works right" it's "my lights don't work even though no one messed with them and they worked fine an hour ago"

There could be a Loose wire coming off and breaking the circuit. Although rare, switches can fail internally.

Still, it's unlikely to be the culprit. A loose wire would been giving intermittent issues as it made and lost its connection till it finally came completely off.

It could be a dead switch (aka one that failed in the off position) though, I'll give you that. Depending on the age of the switch it might even be the issue.
