SwiftData crash: PersistentModel.keyPathToString(keypath:)

I'm distributing an iOS (17.4+) and visionOS (1.2+) app via TestFlight that's using SwiftData.

The most common crash by far is from SwiftData when deleting models from a context using a predicate (first snippet below), but so far I've been unable to reproduce it myself locally (second snippet below). I'm using SwiftData outside of SwiftUI views, via my own wrapper, and converting between my app models and SwiftData models.

Does anyone have any ideas how I could potentially narrow this issue down (or reproduce), or know of any similar issues?

Thanks! — Seb

do {
    try context.transaction { context in
        let predicate = #Predicate<PersistedFeed> {
            $0.id == id
        }
        do {
            try context.delete(model: PersistedFeed.self, where: predicate)
        } catch {
            // .. Omitted for brevity
        }
    }
} catch {
    // .. Omitted for brevity
}
