Group synchronization not permitted due to SID duplication error

In our environment, we are synchronizing from on-premise AD to Azure AD using Azure AD Connect.

In the production environment, we are able to synchronize without problems,

However, in the development environment, some problems have occurred and synchronization of some OUs has been stopped.

This time, we tried to resume synchronization of OUs that contain many groups for verification purposes, but the number of errors reached 5000 and synchronization was stopped.

We know that 4989 of them are SID duplication errors.

In light of the above, I have two questions.

Is it necessary to delete the group in Azure AD?

Is it OK to use MSOnline command (is it necessary to use MS Graph, etc.)?
