I am a support tech and we have a Mac user with the same issue. The user gets invites all the time and adds them to her calendar via an ics file. Out of the blue last week Outlook just started opening the ics in an email message instead of her calendar.

Any news on a fix? She is up to date with Office for Mac 16.43

Hi, am running Monteray on an intel MacBook, with office365, and had the same issue:
under Calendar App preferences, my default calendar app is set to Outlook, but each time I double-clicked on *.ics, it would open Calendar App, not Outlook.
what I had to do is right-click and choose open with, and I noticed that it had CalendarFileHandler selected.
To fix this, right-click on a *.ics file, and select "get info". then go to "open with" and select Outlook, and click on the "change all" button.
hope this helps a fellow mac user
