Xcode 16.2 won't open project

Since updating to Sequoia, Xcode no longer opens some projects.

What I’ve tried so far:

Opening the project directly from the .xcworkspace file, but it still doesn’t open. The app doesn’t crash, but the project simply won’t load, and the UI doesn’t appear.

What I tried:

  • Uninstalled and reinstalled Xcode.
  • Cloned the project from scratch.

I’m currently using Sequoia 15.3.1 on a macbook pro M3.

Sometimes, after restarting the Mac, it works. However, not always—I’ve had it work only twice so far.

Have you any error message ? What type of project is it ? SwiftUI ? Other ?

Do you succeed in opening directly the .xcodeproj file ?

May have a look here: https://codecrew.codewithchris.com/t/xcode-project-xcworkspace-has-been-modified/25740

When I open the .xcodeproj, it launches but crashes after a few seconds, forcing me to quit the app. No error pops

There are all react-native projects.
