@ihf After some hours to try and test some Shortcuts actions, I've found that even if the "search events" action does not work anymore (with last version of IOS and Apple Watch OS), it seems that "get a number of events from a particular calendar" works correctly....
Then, I advice you to save the current Outlines shortcut under another name (I called it "Outlines old") before installation of a new shortcut. I also advice you to check their content to understand how they are different. Also, the "get events" action needs to know the maximum number of events (here 100, up to you to change the value) to get n events at a specified date (here 01/01/2022) in a specified calendar (here "outline").
And, please, test it and give some feedback, thanks.
