i’ve resolved the problem with Developer assistant with this steps

Troubleshooting After a Freeze

  • Force Close UEFN: If it’s locked up, close and reopen the editor.
  • Re-sync or Restore Again:
  • Use Sync Latest or the CLI tool (urc projects snapshots get ) to restore the desired revision again.
  • Check the Output/Message Log:
  • After a successful launch, check the Message Log for errors or missing files.
  • Remove Local Derived Data:
  • Sometimes, deleting the local Intermediate or DerivedDataCache folder inside your project directory can clear stuck states (be sure to back up first).
