So I downloaded the 20.9.89 for mac (simply changed the name of the link above, from msi to dmg), installed it, but then another kind of error appeared when importing the backup dataset:
Interestingly, the previous attempts to import the backup file are still visible on the business page and when opening them, the old kind of error appears. Could this be a problem that replacing an old version with a new one does not actually erase all the files/data in the Applications folder? Anyone has any ideas? Thank you so much in advance.
