I'm not super familiar with Endeavour but are you sure your graphics card drivers are installed correctly? Looks like Endeavour gives you a command line program called Nvidia installer. You can also usually run "nvidia-smi" in terminal normally to check if they're working.
Also, are you on a laptop that uses integrated graphics? Maybe try switching to your dedicated NVidia graphics card.
And I'm seeing that Endeavour lets you choose which desktop environment you run, try switching to another desktop environment like Gnome or Cinnamon.
Looks like you might be able to select which video card takes priority in the Nvidia Control Panel which you should be able to get to by running "nvidia-settings" in the command line.

No, it's a normal desktop PC

It let's you choose which desktop install during the OS installation. If you install multiple desktops enviroments you can choose which one to run with most distros, is not a special feature of EndeavourOS or anything, most distros, if not all, can do it
Try purging your graphics driver. I think Arch based distros use pacman and I'm more familiar with apt so I'm not sure how to do that. Purge the driver and the configurations and try installing the 525 version of the driver and see if that fixes anything.
