I have good news and bad news.
The good news is that the issue seems to have been fixed as of today. I
don't get the error popup, and Help > Dependencies shows pylsp_black
installed and at version 1.21.
The bad news is I'm not sure what fixed it. I realized I made the
mistake of following my daily routine of updating my system, which is
not a good idea when troubleshooting. I checked the changelog dates on
the dependencies for python3-spyder, and the most recently updated were
python3-pygments on April 19, and python3-cookiecutter and
python3-sphinx on March 29.
The only updates today were chromium, chromium-common, and
chromium-sandbox, updated to 114.0.5735.90-2. Maybe those are indirect
dependencies?
