Text typed into Messages or Reminders suddenly jumps around erratically

I have a MacBook Pro 16 inch, late 202, running Monterey v. 12.3. If I type a short message there is no problem, but if it is more than a few lines the text goes berserk. It rearranges words, turns letters into apostrophes, etc. It just happened again -- I copied it and fixed it in email, then cut and copied it back into the message. Then I tried to edit a Reminder entry and it did the same thing.

MacBook Pro 16″, macOS 12.3

1 - Suggest restarting 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 - Does the issue present in this mode ?


3 - 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.


4 - If the issue is present in the dummy account - then this appears to be a System Wide issue.


If the issue persists after the above, please advise.
