 Test this at WordCamp Europe 2025 using WordPress playground and recorded
 2 videos of the tests.

 Before the fix we can observe that a user is successfully created with an
 empty user_nicename which results in the author page link leading to a
 404. https://www.loom.com/share/f23eabfc48974f04919c9ed827ad5126?sid

 After the fix we can observe that if a user's user_nicename would be empty
 then no user is created and an appropriate error is returned.

 Based on these results and a review of the code in the pull request, I've
 approved the pull request.

 Thanks @thehercules for the patch !!
