On macOS Ventura, when I get a Reminders's notification, and then I try to open this reminder through notification, I get "There is no application set to open the document RemindersSharingExtension.appex". The bug has been in Monterey and still is happening on Ventura. It's not always there. It can work for a week normally and then reappear.
MacBook Pro 16″
Running Ventura 13/1 on 2 Apple Computers.
Both signed into the same Apple ID Account.
Both computers are using iCloud and all available Applications for iCloud are enabled.
Reminder does not exhibit this issue
Go figure
1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.
2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading
3 - Does the issue present in this mode ?
4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.
Still issues >>>
5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.
6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.
Still having issue after performing the previous steps 1 - 6 ➡️ ➡️
7 - Download the Application Etrecheck directly from the Developer.
This is a Diagnostic Tool that makes no changes to the computer.
It makes a coherent and readable inventory of both the Hardware and Software used on the computer
The application is free or paid from added features.
The Report will Not Reveal Any Personal Information.

This appears, to these Old Eyes, to be a " Shared Reminder " that is pointing to a Document that is not present and installed on this computer.
Where the Issue is appearing
Links below on Shared Reminders
Use reminders from your internet accounts on Mac - Apple Support (CA)
Assign shared reminders in Reminders on Mac - Apple Support (CA)
In Apple Reminders only iCloud account is in use, the task itself is in Inbox (list is not shared), and the task/reminder itself is not shared, nor does it have any attachment (document, picture, etc.). The same task was generated in the same Mac. Usually Mac's restart solves the issue.
I have restarted the Mac, and now there is no error, until it's just randomly starts happening again.
Edit: And 15 minutes later it gives the same error again...
