Update:  Seems confirmed this is CTools, see critical bug issue.

And this fixed it:

If you are still getting…

If you are still getting this error now, it is almost certainly because your version of CTools after a composer update is 4.0.1, which is knowingly and ridiculously as broken as 3.10.0 was.

You can fix it by adding this to your composer.json file:

        "drupal/ctools": "^3.11",
