Answer 1

Try creating your project without Active Admin. It doesn't seem to support Rails 7 yet.https://issueexplorer.com/issue/activeadmin/activeadmin/7196

Answer 2

As a temporary solution you can disable server_timing in config/environments/development.rb :

   # Enable server timing
-  config.server_timing = true
+  # config.server_timing = true

See https://github.com/activeadmin/activeadmin/issues/7196#issuecomment-1002929616 .
