ExtensionKit Error 15

When attempting to access Internet Accounts I'm given the error "com.apple.extensionKit.errorDomain error 15."


Any ideas what this is or how to resolve it?

MacBook Pro 13″, macOS 13.3

I have this error too and it's preventing me from accessing my mail normally. It cropped up after I used Migration Assistant to migrate the data from my M1 MacMini to my older Intel MacBook Pro; both machines running Ventura 13.3.


A call to Apple Assistance earlier in the day to try and fix the problem was totally unproductive, although I hadn't seen the "ExtensionKit" error message at that point. The phone connection to the Apple advisor was bad, and after the line dropped she never called me back.


I'd really be grateful for help in fixing this problem.
