Ubuntu 20.04: Can't boot, ACPI Error: AE_NOT_FOUND

cv flag

my Ubuntu fails to boot. It gives this error for a few seconds and goes black screen.

I assume it is because of nvidia drivers. I might have messed up some things on the way while working on GPU or upgrading some packages. When I try recover mode --> normal mode I can boot it. Is there a way to fix this? My ubuntu version is 20.04

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.
