You do not have permission to access this information when they click on share and release

Hi, as a line manager user is getting an error "You do not have permission to access this information." when they click on share and release/share and retain button. This is happening when they try to complete one of the tasks of performance documentation.

Although this functionality is working absolutely fine in non-prod and surprisingly all the roles are same between Prod and non-prod.

Any help would be appreciated.

Thanks
