Sometimes big problems have small resolve. Too bad not this one. DISM or DISM.exe no different. The problem is same.

Hi there,

If PowerShell is not working you can try out these methods.

1- Clean install
The simplest way to install Windows Server is to perform a clean installation, where you install on a blank server or overwrite an existing operating system. That is the simplest way, but you will need to back up your data first and plan to reinstall your applications.

2-In-place upgrade
If you want to keep the same hardware and all the server roles you have set up without wiping and reinstalling the operating system, you'll want to do an in-place Upgrade, by which you go from an older operating system to a newer one.

3-Cluster Operating System Rolling Upgrade

You can these options here https://docs.microsoft.com/en-us/windows-server/get-started/install-upgrade-migrate#license-conversion-1

Clean install is it solve, but extreme possibility. Before buy licence key for Standard edition I was finding out optionst for convert Edition and I was assured, os it is possible.

Yes, it is possible to do but not for this one in this broken state. Here one for older 2012/2016 but steps are the same for Server 2019
https://docs.microsoft.com/en-us/windows-server-essentials/migrate/transition-from-windows-server-2012-essentials-to-windows-server-2012-standard

If there were already a domain you wanted to preserve then you can easily do that.

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

The above procedures, which are listed on the site (more webs) I have read. My question here are is last chance before reinstall. I wanted to avoid new install database server and install specific software, which are dificult for setting .

This one is badly broken you could try a repair install by running setup.exe from the root of install media, but time may be better spent standing up a new one, patch fully, migrate the roles over and move on.
