All data gone - help

Main file - Nestle Master file FY24 , i created workflow when checkbox "completed" is triggered that row will be moved to Nestle Master file - COMPLETED. When i start checkinoff boxes for "completed" My whole Master file was completely erased. When i checked activity log it says rows are moved with automatization but even my Master-Completed file is blank now. All my project data from both my files are gone. Please help and advise.
