Other Configuration Manager-related features and issues
Hi @SJU2402 ,
Could we check if we used the Windows Internal Database or use SQL? It is recommended that we use SQL.
According to your description, the problem is related to the SUP/WSUS. We could try to remove SUP role then remove WSUS role and cleaning DB while removing the role, and install WSUS again.
Here is the similar post we could refer to:
