Dependencies can be mentioned in the composer.json
Enable the devel_kint_extras module and go to the extend and module page , you will see a warning in the module description that incompatible with version. Also a warning will show in the status report. Please refer the screenshot attached.
Either remove the version requirement from the dependencies (it can be there in the composer.json). Or make it only require without version dependencies:
- devel:devel (>=5.x) //this will give a warning
versions used :
"drupal/devel": "5.x-dev@dev",
"drupal/devel_kint_extras": "^1.1",
Closed: works as designed
1.1

Seems like Drupal is having trouble figuring out the version of Devel you're using. Is it possible that you're requiring a dev version of Devel? You can use the Composer Deploy module → to make sure version info is always added to info.yml files.
