ValueTransformer currently crashes XCode SwiftUI preview

I have a working ValueTransformer that runs fine in simulator/device, but crashes in SwiftUI Preview. Even though they are the same code.

Here is my code

import Foundation

final class StringBoolDictTransformer: ValueTransformer {
    override func transformedValue(_ value: Any?) -> Any? {
        guard let stringBoolDict = value as? [String: Bool] else { return nil }
        let nsDict = NSMutableDictionary()
        for (key, bool) in stringBoolDict {
            nsDict[key] = NSNumber(value: bool)
        }
        do {
            let data = try NSKeyedArchiver.archivedData(withRootObject: nsDict, requiringSecureCoding: true)
            return data
        } catch {
            debugPrint("Unable to convert [Date: Bool] to a persistable form: \(error.localizedDescription)")
            return nil
        }
    }

    override func reverseTransformedValue(_ value: Any?) -> Any? {
        guard let data = value as? Data else { return nil }
        do {
            guard let nsDict = try NSKeyedUnarchiver.unarchivedDictionary(ofKeyClass: NSString.self, objectClass: NSNumber.self, from: data) else {
                return nil
            }
            var result = [String: Bool]()
            for (key, value) in nsDict {
                result[key as String] = value.boolValue
            }
            return result
        } catch {
            debugPrint("Unable to convert persisted Data to [Date: Bool]: \(error.localizedDescription)")
            return nil
        }
    }

    override class func allowsReverseTransformation() -> Bool {
        true
    }

    override class func transformedValueClass() -> AnyClass {
        NSDictionary.self
    }
}

and here is the container

public struct SwiftDataManager {
    public static let shared = SwiftDataManager()

    public var sharedModelContainer: ModelContainer

    init() {
        ValueTransformer.setValueTransformer(
            StringBoolDictTransformer(), forName: NSValueTransformerName("StringBoolDictTransformer")
        )
        let schema = Schema([,
            Plan.self
        ])
        let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)

        do {
            sharedModelContainer = try ModelContainer(for: schema, configurations: [modelConfiguration])
        } catch {
            fatalError("Could not create ModelContainer: \(error)")
        }
    }
}

and the model

@Model
final class Plan {
    @Attribute(.transformable(by: StringBoolDictTransformer.self))
    var dict: [String: Bool] = [:]
}

I would get that container and pass it in appdelegate and it works fine. I would get that container and pass it inside a #Preview and it would crash with the following:
