Creating a database and then renaming it or copying it to another within the same instance

Neo4j 4.3
Desktop 1.2.7

I want to be able to create a database, and then either drop an already existing database and rename the new database that of the recently dropped database, or create a duplicate of the newly created database and give it the name of the recently dropped database.
Ideally I would like to, in some form, save an instance or the database that is to be dropped/replaced, in case of any issues during the process, the procedure can then revert back to the original database.

Backup the existing database into data/dumps folder by running this command in the terminal window:

bin/neo4j-admin backup --backup-dir=data/dumps --database=xyz

Restore this backup as a different database:

bin/neo4j-admin restore --from=data/dumps/xyz --database=xyzz --force

or if this is a single instance you might want to consider using

i have tried using these listed above but when creating the database i get an error:

I tried to do a copy, create a back up and force restore from it to a newly named DB, and nothing seems to work. I noticed when I created the backup or copy that the directory would be owened by root. so I ran chown -R neo4j:neo4j against the directory to make sure it that was not the issue before i created the database in the browser, but still get the same error.

What version of Neo4j?

Does the logs/debug.log provide any detail as to why it doesnt come up?

This is what I am seeing in the logs:
