This was the problem,
This is test script. One line of PHP code:
https://seeme.baby/test.php

503 error in result.
Because function ‘transliterator_transliterate’ failed to execute on your server.

Exactly the same PHP script on my own server working properly:
https://takereal.com/test.php

File ‘wp-content\plugins\buddypress\bp-core\classes\class-bp-attachment.php’ updated
to prevent ‘transliterator_transliterate’ execution.

old line #297:
if ( function_exists( ‘transliterator_transliterate’ ) && seems_utf8( $retval ) ) {

My version:
if ( 0 && function_exists( ‘transliterator_transliterate’ ) && seems_utf8( $retval ) ) {

Function ‘transliterator_transliterate’ used in the ‘class-bp-attachment.php’ only.

File name sanitized in another way, without ‘transliterator_transliterate’ function.
‘class-bp-attachment.php’ has code to sanitize file name
without ‘transliterator_transliterate’ function.

From logs gives this error
2022-08-26 10:06:27.739089 [NOTICE] [566017] [5.203.157.99:2859:HTTP2-1847#seeme.baby-443] oops! 503 Service Unavailable

from debug i get

That’s what I started with: disabling plugins one by one, but that didn’t show any issues. I noticed the code was only appearing on Buddypress pages, so then I kept Buddypress active and one-by-one activated, checked, and then deactivated each plugin until the code reappeared.

It takes a super long time, but it’s really the only way to really find issues like this (that I know of).

I also use the Health and Troubleshooting plugin to do this, so the site doesn’t appear any different to anyone non-admins. That means people can keep using the site (I have courses with Learndash, so this is a big one!) while troubleshooting

Thank you Michael, it works using Code Snippets with this code:
/**
* Exclude Users from BuddyPress Members List by WordPress role.
*
* @param array $args args.
*
* @return array
*/
function buddydev_exclude_users_by_role( $args ) {
// do not exclude in admin.
if ( is_admin() && ! defined( ‘DOING_AJAX’ ) ) {
return $args;
}

$excluded = isset( $args[‘exclude’] ) ? $args[‘exclude’] : array();

if ( ! is_array( $excluded ) ) {
$excluded = explode( ‘,’, $excluded );
}

$role = ‘administrator’;// change to the role to be excluded.
$user_ids = get_users( array( ‘role’ => $role, ‘fields’ => ‘ID’ ) );

$excluded = array_merge( $excluded, $user_ids );

$args[‘exclude’] = $excluded;

return $args;
}

add_filter( ‘bp_after_has_members_parse_args’, ‘buddydev_exclude_users_by_role’ );
