    we had the same issue and able to figure out what was causing this error.

    we have On-prem Security Group for each O365 license, after one of our O365 license expired we have deleted the assosiated AD security group, but didn't remove the Licensed group associated with the license in Azure AD.

    THIS IS MY FIX as I did indeed have a non-synced OU (it used to be synced, with members in it; empty and non-used now) with an assigned license.:

    Did you delete any security group associated with a license? also, moving the security group away from non-synced OU after creating a Licensed Group (in Azure AD) on a license gives you the same error... check which licensed group in Azure is attached to the non-synced (or deleted) security group in on-prem and then deleting that Licensed Group on the License should resolve your issue, i may be misleading but just want to give my suggestions.

    here is an article to trace out the issue.. https://timmcmic.wordpress.com/2021/05/26/azure-ad-connect-sync-error-113/amp/
