Nvidia driver install has disabled tty7 and cant start display manager (fresh Debian install)

Ive just installed a fresh install of Debian 10 and can no longer get into the default tty7 that the main system would normally boot into.

I tried running sddm from the console and this is the error i get:

[10:41:33.108] (II) DAEMON: Initializing...

[10:41:33.113] (EE) DAEMON: Failed to read display number from pipe
[10:41:33.114] (EE) DAEMON: Display server failed to start. Exiting

running a startx command will bring me back into KDE however.

Other things I noticed while troubeshooting is there is no /etc/X11/xorg.conf file

I had other issues like a low res on bootup, I was able to fix this by changing the line in /etc/default/grub

to read GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
and that fixed that, but its impossible to get into tty7.
It was not doing anything when doing ctrl+alt+f7 before, but now I do get a blinking cursor like others are reporting.

Any help would be appreciated.

Thx :)
