20.04 crashing on dpkg --configure -a

PC keeps crashing when I'm trying to fix dpkg by running dpkg --configure -a It crashed and went to basic video so I tried to downgrade the nvidia driver to 460 (495 has been working fine, didn't update anything else) but apt is locked and everytime I try to fix it it crashes; black screen. I've tried from the recovery console as root, same thing. RTX 2060 Ubuntu 20.04.3

There isn't anything in the logs that I can see. Temperatures seem fine.

This is what is says on the screen when it crashes:

update-initramfs: deferring update (trigger activated)
update-initramfs: Generating /boot/initrd.img-5.4.0-91-generic

Saw this answer and thought it migth be worth a go reinstalling gcc.

I booted to live cd and chroot'd in and killed apt and removed the apt locks bc it was still telling me to fix dpkg.

sudo apt-get install gcc said that it was installed but now set to manual. ran sudo dpkg --configure -a again and, though all the cpu's went to 100 for a worrying amount of time it completed successfully and is now working fine.

**** edit ****

The problem came back and in the end following this answer removing duplicate drivers seemed to do the trick.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
