I saw a comment from September 2020 where the same error message was resolved by updating SQL Server to "the latest CU".

With that in mind, what version of SQL Server 2019 are you running?

A quick way to check is running "Select @@Version"

    thanks for answer.

    yes i also saw  this solution. but i updated my system via Windows update few days ago.
    "Select @@Version" shows:
    Microsoft SQL Server 2019 (RTM-GDR) (KB5065223) - 15.0.2145.1 (X64)   Aug 13 2025 11:31:46   Copyright (C) 2019 Microsoft Corporation  Standard Edition (64-bit) on Windows Server 2019 Standard 10.0 <X64> (Build 17763: ) 
    but i am not sure it is "Latest CU"

      Microsoft SQL Server 2019 (RTM-GDR) (KB5065223)

      RTM-GDR means "Release to market" and I don't remember what GDR's short for.
      Release to market means not updated at all.

      The KB number is the "patch name", and is searchable online.

      I would suggest visiting this page and download the latest cumulative update (CU32) for SQL Server 2019.
      Latest updates and version history for SQL Server - SQL Server | Microsoft Learn

      Best of luck.

        yes. i did:

        " I would suggest visiting this page and download the latest cumulative update (CU32) for SQL Server 2019.
        https://learn.microsoft.com/en-us/troubleshoot/sql/releases/download-and-install-latest-updates

        this is next step where im stuck.
        i cannot use "latest cu" coz before i installed (with windows update) newer security patch for sql server. so now "latest cu" setup says - "u already have newer version". if i uninstall security patch, it disapers from Add/remove programs, but CU32 setup still "see it somwhere" and won't run.
        but anw thanks for suggestions.
