Hi,
Did you try running the cmdlet many times, and on different SCOM management servers?
Here's a thread discussing the same issue:

That's likely because you moved the SCOM DB to another server at some point and something went wrong in the process.
Read here on how to fix it (careful, this link is for 2016 and 2019 only, there is another article in kevin's blog for 2012 R2 ) : https://kevinholman.com/2017/08/27/scom-2016-event-18054-errors-in-the-sql-application-log/
