The AppleCare tech attributed that to a need to upgrade my OS. My options are the later version of Ventura 13.6.1 or Sonoma 14.1.1, which the AppleCare person described as "next generation," with more significant changes than I'd get with the newer Ventura.
There's no reason necessarily to upgrade to Ventura as it has some UI modifications…but OTOH there's no real reason not to upgrade to it as well. I upgraded my M1 MBP the day or two after Sonoma was released and LR Classic and PS work just fine. I would take a look at one of the many "what's new in macOS Sonoma" articles on the various macOS related websites and make sure you're ok with what it does first. The biggest change is that by default clicking on the desktop hides all your windows…I don't like this particular change but it's easy enough to revert it to the old way in System Preferences -> Desktop.
Overall…probably time to upgrade…but make sure you have backups, clones and all that jazz beforehand.
