 Hello @soulfly1506,

 Welcome to WordPress Core's Trac :) Thanks for reporting the upgrade issue
 you experienced. I'm sorry for the delay in responding to you.

 Huh that's interesting the error occurred when upgrading from 6.4.0 to
 6.4.1. Why is it interesting?

 `print_emoji_styles()` was deprecated in 6.4.0. The function moved from
 the `wp-includes/formatting.php` file to the `wp-includes/deprecated.php`
 file in 6.4.0, not in 6.4.1.
 [https://core.trac.wordpress.org/browser/tags/6.4/src/wp-
 includes/deprecated.php#L5904 See it here in the 6.4 tagged release file].

 Having this error occur when upgrading from 6.4.0 to 6.4.1 suggests to me
 the initial upgrade to 6.4.0 was incomplete. How so? The function likely
 still existed in the `wp-includes/formatting.php` file and did not exist
 in the deprecated file, meaning neither file was updates when upgrading to
 6.4.0.

 The error received when upgrading to 6.4.1 indicates the `wp-
 includes/formatting.php` file was not upgraded. If you open that file, do
 a search for the `print_emoji_styles()` function.

 To resolve, I'd suggest doing a full upgrade again to 6.4.1, just in case
 there are other files that also did not get replaced/updated. How? See
 this [https://wordpress.org/support/topic/read-this-first-wordpress-
 master-list/ Support post for more information] and/or
 [https://wordpress.org/documentation/article/updating-wordpress/ Manual
 Update > Updating WordPress].

 As there are no other reports of the same issue, I'll close this ticket.
 However, @soulfly1506 if the problem persists, please reopen the ticket.
