email "this application cant be opened" error 600

When I get emails with a link to a website I get an error message "unable to open this application" -600


Why have I started getting this message with all emails with a link in them?

MacBook Pro 13″, macOS 12.7

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?


Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.


If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.


Does Mail crash if no internet?


Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.


If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.
