You may got error while installing new module via drush
for example:
When you try to install devel and devel_kint_module or any other module, will be getting similar error
Configuration objects(system.menu.devel) provided by devel already exist in active configuration.
Here is the solution to overcome this issue
drush config-delete <configuration object you wanted to delete>
In my case, I need to delete system.menu.devel.
drush config-delete system.menu.devel
