BuddyPress.org

All of a sudden I can no longer manage users of a specific group, whether from the front end or back end. The manage-members page loads fine, but the member list is blank. The member count is correct in the back end and are all present in the DB. Members can also still access the group. Member management of other groups is unaffected. Depending on the browser, I get different console errors:

Chrome:

I have:

1. Tested for plugin conflicts. Even stripped down to just BP running, error persists.
2. Tested for theme issues. Error persists.
3. Disabled bp-custom. Error persists.
4. Restored theme functions.php to default. Error persists.
5. Nothing in the server error logs.

Not sure where to turn next. Went as far as to update all plugins and theme on a staging version but no change. I really don’t want to have to recreate the group – it has private docs assigned to it.

EDIT: I have found that if I remove the last members to be added (7 total) from the database that the list is restored. However, if I add even one of them back, the list disappears again. Adding any other non-member WP user that is not a part of the seven I deleted from the DB works fine.

WP 5.9.3
BP 10.4.0
Link to site wouldn’t be useful as all of the groups are set to private or hidden. Can potentially provide access privately.
