Deleting the user config has fixed this for me.

C:\Users\[user]\AppData\Roaming\IsolatedStorage\StrongName.cc1bdxpzcw0hn1lld3fth5uorokeuzbv\AssemFiles\dsac.exe.usersettings.dat

Hi Ahmed,

Seems like a DLL corruption, does it show DLL details? try to register it again, regsrv32 path to the DLL.

Hello

Thank you for your question and reaching out.

It could some corruption in Windows OS system files.

1. Disable any Antivirus program or Windows firewall you may have for temporary purpose.
2. Cleanup below Temp folders
   C:\Windows\Temp
   %USERPROFILE%\AppData\Local\Temp
3. Run below DISM commands from elevated prompt.

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

From https://learn.microsoft.com/en-us/answers/questions/547502/servermanager-will-not-launch-on-2-2019-servers

If I copy both EXE files from %windir%\system32 to C:\Temp\

C:\temp\dsac.exe
C:\temp\ServerManager.exe

I can start both, Server manager and ADAC.
