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).
