Thank you for the response. The app I am working on is a macOS app. Does that work with the workaround too? Also, do you know when the bug will be fixed?

Thanks for the response. Yes, it could reproduce it with Thread 1: Fatal error: Failed to create the model container: SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer, _explanation: nil) error in DataModel.swift. macOS: 15.1 (24B83) Xcode: 16.1 (16B40)
