Hello,
This is most likely due to a corrupt file. See Bug #89982 as example. Also seems you are using a very old LO. Current version is 5.4.x - consider upgrading.
If in fact corrupt, only probable recovery may be a backup copy.

Thanks very much.

Your welcome. If you need further help, don’t hesitate to ask. It may be possible to save at least data if not more even from a corrupt file.
