Hi, I have seen this error elsewhere online. I have gone to mmc to enable the snap in and I still have had no fix. My computer is running Windows Server 2022, SQL Server Express 2022, and SSMS. I have reinstalled, repaired, and all of the other tricks. Help!
Solution: Re-register the Configuration Manager Snap-In Manually
-->Open Command Prompt as Administrator
-->Run the following command:(For SQL Server 2022, the version folder is 160. Adjust the path if yours is different.)
-->cmdmofcomp "C:\Program Files (x86)\Microsoft SQL Server\160\Shared\sqlmgmproviderxpsp2up.mof"
-->Restart your machine
