Wp 5.5 bug: Cannot delete multiple users

[quantum_leap]

After updating to WP 5.5, I can't delete multiple users. I think there is something wrong with the wpnonce response?

Steps to reproduce:

1) Clean WP install with no plugin and default theme.
2) Create 3 test subscriber users
3) Try deleting all of them at once from the admin (not one by one)
4) I was expecting a confimation message for the users' deletion, instead, you get the message "The link you followed has expired. Try again". When you try again, you get the message "The link you followed has expired."
5) Delete users, and downgrade to previous WP version 5.4.2
6) Recreate the users
7) Try to bulk delete them
8) Users get deleted as expected

Hey @quantum_leap. Welcome to Trac and thanks for opening this.

I can confirm I can effectively reproduce the issue on WordPress 5.5 and that it's working correctly 5.4.2.

Exploring to see where this was introduced.

So, looks like this happens very randomly on 5.5. Not seeing any obvious reason for that now.
