Google only found this link to the OpenOffice community forum: AutoSave v AutoRecovery. No real solution is offered there, except to disable autorecovery. MAybe it helps if you eset your user profile. Shut down LibreOffice, including the Quickstarter if you still use that. Then rename the user profle folder - the folder called “user” - important: rename it, don’t just delete it, if you have many customizations and macros.
