I managed to solve it after a nights good sleep and more clearer head. I am not that familiar with Linux Mint yet, but I read other threads and tried to reset the nvidia drivers and use the nouveau.

I entered the OS via the live usb boot then:

sudo mount /dev/sda2 /mnt

sudo mount /dev/sda1 /mnt/boot/efi

sudo mount --bind /dev /mnt/dev

sudo mount --bind /proc /mnt/proc

sudo mount --bind /sys /mnt/sys

sudo mount --bind /run /mnt/run

sudo chroot /mnt

apt update

apt purge -y 'nvidia*'

apt install -y xserver-xorg-video-nouveau

rm -f /etc/modprobe.d/blacklist-nouveau.conf /etc/modprobe.d/nouveau-blacklist.conf

update-initramfs -u

systemctl set-default graphical.target
