Unable to create backups with buddy, error access denied

Hi, I am trying to create backups with @Backup Buddy24 but am unable to do so, when I checked the console and I found this Javascript Error in it. how can I fix it?

Error #82389: A javascript error occured which may prevent the backup from continuing. Check your browser error console for details. This is most often caused by another plugin or theme containing broken javascript. See details below for clues or try temporarily disabling all other plugins.
