Unable to delete/remove user from group

[Deleted user]

Hi folks, I upgraded my Confluence environment to the latest 8.4.1.  We have one user that is just unable to login.  We do have LDAP -> AD and his AD account is fine.  When browsing the user group list, I am able to browse to the next couple pages before receiving 'Oops - an error has occurred'.  If I click on show 100, I get that error page right away.  If I try and remove the problematic user from the group, I get an error.  See images below.  I've attempted a re-sync to no avail.

In the atlassian-confluence-security.log file i see..

This is bad image but in the group user list, his User and Email columns are blank, only his Username shows..

any help is appreciated.
