Mac OS : cannot save any new document

I just downloaded the last version of LibreOffice but anytime i create a new Calc doc, i cannot save.
When i click on Save / Save as / Export, it just load with the rainbow loading icon for a few seconds, and then nothing happens.
Has it occured to anyone here ?

Have you given the new version Full Disk Access? You might have to remove access permission and then apply it again so the new version gets it.
