I'm seeing this on a user's Mac. Did you ever find the reason for the crash?

Did you ever find a solution to this? I'm experiencing a similar problem.

Lost 3 hours trying to make this work. I managed to get it working using: let localizedString = LocalizedStringResource("my.intents.string.id %@ %d", defaultValue: "my.intents.string.id \(myString) and \(myInteger)") and then like this in Localizable.strings: "my.intents.string.id %@ %d" = "%@ and %d more";

The only thing that worked for me, unfortunately is downgrading to Xcode 13.2.1
