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.
