G15 5530 RTX 4050 Ubuntu 20.04 not booting (black screen) after installing drivers

I have installed liquorix but Ubuntu does not boot after that and freezes. I booted by changing ‘quiet splash’ to ‘nomodeset’.
Now I am trying to install the firmware package you provided as the root user by the dpkg -i *.deb but it gives the following error:

dpkg: regarding linux-firmware_20230919.git3672ccab-0ubuntu2.1_amd64.deb containing linux-firmware:

uname -r gives ‘6.3.13-1-liquorix-amd64’.
