Magento 2: Change the “URL Key” and save the category “The value specified in the URL Key field would generate a URL that already exists.”

When change the “URL Key” and save the category then throw the below error.

This store Migrate Magento 1.9 to Magento 2.3.5-p1 and used multi store view.

Error:

The value specified in the URL Key field would generate a URL that already exists.
To resolve this conflict, you can either change the value of the URL Key field (located in the Search Engine Optimization section) to a unique value, or change the Request Path fields in all locations listed below:

- fitness-equipment/strength/kettlebells.html

- fitness-equipment/strength/dumbbells.html

- fitness-equipment/strongman/hammer.html

I have try below solution but not fixed the issue:

    - Generate category url via https://github.com/olegkoval/magento2-regenerate_url_rewrites module
    - use command for genrate the category url: php bin/magento ok:urlrewrites:regenerate --entity-type=category
