Your file wasn't saved because we couldn't merge your changes with changes from someone else

Hello, we're encountering a recurring issue while sharing a file on SharePoint. The error message "Can't save your changes - Your file wasn't saved because we couldn't merge your changes with changes from someone else" frequently appears. Despite attempting various publicly available solutions, we haven't found one that resolves the issue. The Excel file contains formulas and timestamps and is being edited by approximately 15 individuals simultaneously. This error starts occurring for all colleagues when inserting a new row or adding a timestamp. Where could the problem be originating from?
