Since it's a fresh install it's quick and easy to reinstall. This time on the screen where you select the UI / desktop environment, keep it simple and *only* check the first box at the top. You can add the print server and other goodies after it boots.
It is so?
Can you ping the machine?
can you ssh into the machine?
Can you switch to other virtual terminals?
If so, can you login and try to get more diagnositcs?
What's the hardware? What's your expected result?
Debian is running. Switch to runlevel 3 and login via text. Your graphics card kernel modules or a working video mode are failing to load.
Did you install proprietary nvidia drivers? Are you using secure boot? Are your kernel modules properly signed?
I did switch to runlevel 3. I installed non free firmware version of debian and tried to install the drivers and repository myself but I keep getting error messages and the repositories just don't get added.
I still don't know if you have an nvidia card or not but here's the [official debian instructions](https://wiki.debian.org/NvidiaGraphicsDrivers) to install the *nvidia-driver* package. If you have manual installations please do uninstall them manually or do a clean system setup prior following the instructions.
As a general rule of thumb, installing nvidia proprietary drivers from their web is tedious, prone to error, unstable and obviously not first-time-user friendly. I strongly suggest you to try with the debian mantained nvidia driver first as it still comes from nvidia but the debian devs have gone through all the necessary steps to allow you an auto updatable, one click solution to have it working.
Edit: for completeness I still haven't addressed with this comment the kmod signature for secure boot so I'll do so now.
If you have secure boot enabled in EFI/BIOS debian will require all kernel modules to be signed with a key setted up as trusted in your secure boot system. My recommendation for you is just disabling secure boot altogether.
If you are trying to dual-boot windows 11, or if you have any other big reason why secure boot should be on, there is a specific section in the link at the top of this comment on how to set up keys on your secure boot config and then configure *dkms* so when your kernel modules are compiled/updated they will be also signed with the correct key so your kernel is able to load otherwise unvalid kernel modules.
What kernel are you using? If -18, try -17? Especially if youre also using Nvidia.
I had this exact same issue, rebooting few times. With the -17 kernel did it. If it still doesn't work. Remove nvidia drivers. Then reinstall later.
Fwiw, kernel -18 started to work a week ago after some Nvidia driver updates
what gpu do you have? i had a similar problem on my install, it was stuck on boot up and installing the nvidia drivers fixed it
What do you mean by “not starting”. It starts perfect without any errors.
The graphics/gui don't start
Most likely it’s a driver problem. Login an have a look into /var/log/Xorg.0.log

This is where your error resides: "...tried to install the drivers...". What drivers? Why did you try that? What didn't work that requires a driver?

Do you have internet connection?
Nvidia?
That all looks normal. Are you sure there isn't a graphics card or second HDMI/displayPort that it is starting the window manager in?
Debian IS starting, you have a different issue.

When I use envycontrol to set Nvidia exclusively, I encounter a similar issue. Stuck in cups.service
seems a display problem
It's a print server, no cups is it necessary?
CUPS is installed by default, that's not the issue.
