 Running WordPress core v6.0 with PHP v8.0.14, all plugins turned off, and
 a default theme (on a long running installation of WordPress), we're
 getting:

 {{{
 Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of
 type Countable|array, int given in /.../wp-admin/user-edit.php:303 Stack
 trace: #0 /.../wp-admin/profile.php(18): require_once() #1 {main} thrown
 in /.../wp-admin/user-edit.php on line 303

 There has been a critical error on this website. Please check your site
 admin email inbox for instructions.
 }}}

 The code on that line suggests it could be addressed via:
 {{{
 if ( is_countable( $_wp_admin_css_colors ) && count( $_wp_admin_css_colors
 ) > 1 && has_action( 'admin_color_scheme_picker' ) ) : ?>
 }}}
