Following Big Sur update 11.3.1, LibreOffice unable to save files

Cannot save any LibraOffce files since Apple OS Update to 11.3.1. Please help

Thank you.

What is the fault that you tracked down and identified as Calc’s fault?

You probably need to give LibreOffice full disk access from System Preferences > Security & Privacy. See this site on how to do it if you aren’t sure: Explained: What is Full Disk Access & Full Permissions on macOS Mojave .

If you already gave full disk access previously, try removing it and then give access again. Cheers, Al
