Restoring domain: re-creating MySQL user fails when too long

Help - When I want to restore the tar.gz from one server to another one, I come across the following problem. How can I manage it?

Operating system:
Ubuntu 20

OS version:

Restore failed : SQL drop user if exists ‘xxxxxx@xxxxxxxxxxxxxxx’@‘localhost’ failed : String ‘xxxxxxxxxxxxxx@xxxxxxxxxxxxxxx’ is too long for user name (should be no longer than 32)


I’m facing the same issue.
How can this limit be changed?

Any help on this?

I’m stuck restoring the domain because of this.
