abhijeetsatpute → created an issue.
I faced this issue today after upgrading to Drupal 10.1.6
Class "Drupal\\at_core\\Theme\\ThemeConfig" not found" at web/themes/contrib/adaptivetheme/at_core/includes/preprocess.inc on line no. 27.
I had uninstalled
at_tool →
module.
For me it fixed after installing at_tool.
