i can't save anything on my map

Hello @Jopen-YT ,

You are getting error 778 when attempting to write to the /.urc/urc.sqlite file in your project directory. This error means SQLITE_IOERR_WRITE.

Common causes:

  • The Windows user might not have enough permissions to write to that location.
  • The HDD might be full.
  • The urc.sqlite file or /.urc directory might be read-only.
  • A hardware error.

You could try to see if you can open your urc.sqlite file using 3rd party software. There are several Sqlite database viewers available. That way you can at least ensure your database isn’t corrupted.

If you have done regular check-ins of your project using the CHECK IN CHANGES button on the bottom right of the editor, you could delete your project directory and re-download it through the UEFN project browser.
only do this if you did regular check-ins - you risk losing uncommitted work this way
