Hi,
It can be solved on following ways and I tried it.
Always backup files are available for the file realms.nst , SecurityGroups.nst in the UM folder data\RealmSpecific.
Please restore and restart the UM.
Or else you copy and use that from different environment.
If both options didn’t work. update the file SecurityGroups.nst & Realms.nst which exist in the same folder. Though these files are encryted. you can modify in few places. I have removed group names and updated to Everyone on both files. It solved the issue and UM ACL setting restored withEveryone allow options.
If you need more detailsl let me know. Happy to Help you.
Thank you
