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.
