Running updatedb fails with UnknownExtensionException error I am attempting to update my site's database after updating three modules: Configuration Update Base, Search API, and Simple XML Sitemap. Running drush updatedb produces the following error:

I have confirmed that Devel and all of its submodules (including devel_generate and devel_generate_example) are installed. I have attempted deactivating, uninstalling, and reinstalling them, but I am still getting the same error. Does this look familiar to anyone?
Drupal can't find the module when it's scanning the codebase. You'll have to debug to figure out why. Run drush eval 'print_r(array_map(function ($ext) { return $ext-&gt;subpath; }, \Drupal::service("extension.list.module")-&gt;getList()));' to have Drupal dump what modules it can see and try see why it can't find the install location location (file permissions?).
