Unable to boot into live usb after grub menu. Blinking cursor on top left only

[MagicCraftMaster]

I’m trying to install Manjaro Cinnamon 21.0.4 on my newly built computer but every time I boot the live USB after getting past the grub menu and select either free or proprietary drivers I get just a black screen with the blinking cursor. When entering a TTY shell it appears that LightDM is crashing with exit code 1. It seems to be coming from Xorg as that thinks it cannot see my screen even though all of my hardware is visible. I’ve tried just about everything I could find but to no avail. As I said it’s a live USB for installing so I can’t save anything. What could I possibly do to get past the issue and install as normal with the fix applied as well?

Blinking cursor when installing from live USB

What kernel is your ISO running? You probably need a recent kernel for this graphic card (5.12). //EDIT: If you have access to a working Manjaro (probably can do it from another OS but the guide will be for Manjaro specific commands), and if you want to try, follow this guide to build a custom Manjaro ISO, and tell it you want to create a full ISO for Gnome on Stable branch with kernel 5.12: https://wiki.manjaro.org/index.php/Build_Manjaro_ISOs_with_buildiso for Gnome buildiso -f -p gnome -k…

Basically you probably need to boot an ISO with latest kernel (5.12) because of your recent video card.

//EDIT: also now I think about it, you probably can create your custom ISO with kernel 5.12 from GitHub following and adapting this video tutorial if you don’t have access to another working computer
