Time Machine "Restore to..." Doesn' Work

Since updating to Ventura, Time Machine's "Restore to..." function doesn't work like it used to. It doesn't show me a dialog to select a folder (that's what the ellipsis means), it just starts copying everything to the original folder. And there's NO WAY to cancel the copy that I can find. I've had to force quit the Finder a few times.

Is it still possible to restore from a backup without overwriting the original? If so, how?
