first of all you need to wait (as long as the installation is completed). Also probably you may need to reboot after installation.
If it was a new install you ought to start over again and reinstall it. You may also try to remove packages belonging to that group, but that can be difficult.
Would be nice to see if there were any errors...

Should I just group remove "Server with Gui" or there is any specific package that I need to remove.

probably works, but actually I cannot guarantee anything.

Be aware of the difference between environments (environment groups) and regular groups. Server with GUI is an environment:
Code:
$ dnf -q list ids Server\*
Available Environment Groups:
   Server with GUI (graphical-server-environment)
   Server (server-product-environment)
It includes a number of regular groups (some of them mandatory, and some optional):
Code:
$ dnf -q info graphical-server-environment
Environment Group: Server with GUI
 Description: An integrated, easy-to-manage server with a graphical interface.
no group 'dns-server' from environment 'graphical-server-environment'
 Mandatory Groups:
   Common NetworkManager submodules
   Container Management
   Core
   Fonts
   GNOME Desktop Environment
   Guest Desktop Agents
   Hardware Monitoring Utilities
   Hardware Support
   Headless Management
   Input Methods
   Internet Browser
   Multimedia
   Printing Client
   Server product core
   Standard
   base-x
 Optional Groups:
   Basic Web Server
   Debugging Tools
   FTP Server
   File and Storage Server
   Guest Agents
   Infiniband Support
   Mail Server
   Network File System Client
   Network Servers
   Performance Tools
   Remote Desktop Clients
   Remote Management for Linux
   Virtualization Client
   Virtualization Hypervisor
   Virtualization Tools
   Windows File Server
AFAICT, only one environment may be installed at any given time. In order to replace Server with GUI with Server I'd first mark Server with GUI as removed without physically removing its packages, then install and upgrade Server.
Code:
sudo dnf group mark remove graphical-server-environment
sudo dnf group install server-product-environment
sudo dnf group upgrade server-product-environment

Correction. The first two commands in my previous post should be read
Code:
dnf -q grp list ids Server\*
and
Code:
dnf -q grp info graphical-server-environment
respectively. Sorry for this.
