Ubuntu boot screen flashing after update

I'm using Ubuntu 20.04 and, during the power-up, the boot screen starts to look like this(video). And takes a long time to get to the login page. This is my laptop(Dell Inspiron 15 with a nvidia 840m) and I don't use it often but I did a normal sudo apt upgrade before this started happening.

About 2 times I got as "A start job is running for hold until boot process finishes up(time/no limit)", now I'm not getting it. I tried doing a sudo apt update and a sudo apt upgrade.

Also, It looks like my lap keyboard is spamming the tab key(not 100% sure on the exact key, and could be a hardware issue.) Currently, I'm using an external keyboard and disabled the inbuilt one. I'm mentioning this keyboard issue it could be connected cause both happened simultaneously.

Will removing splash screen help? Thanks.
