Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

I've used Zotero for about 8 years with synchronization of the papers.
However, I got following error message after I re-installed Zotero and tried to synchronize the papers yesterday (06/08/2023).

Does anyone know what this error message is about?

Many thanks.
