Will not boot into graphics mode now

After the update of libopenssl1_1-1.1.0i-lp151.8.3.1.x86_64 and a reboot, I can no longer get into graphics mode. Xorg.0.log says:

But I did update the NVidia drivers a while ago and have not rebooted since.
How do I fix this?

Graphics card is NVidia GM107GL [Quadro K1200]
