The keyboard and mouse are unresposive or doing strange things and on-screen keyboard is unresponsive or malfunctioning as well

I have Ubuntu 21.10. and after 1 month, I'm experiencing unresponsive keyboard or keys doing something different to what it's meant to. The mouse also does the opposite of what it's meant to do zoom instead of scroll etc. Even the on-screen keyboard is unresponsive and has the same result as the physical keyboard. I'm unable to type in Terminal and I'm unable to get into BIOS in start up.

But when I first turn on the laptop and need to log in the password works, the keyboard does not malfunction. Only after this it becomes unresponsive.

The laptop is 2 years old but has never been used because it was 100% laggy/un-usable on windows 10, so it's been stored in its box until a month ago and upgraded to Ubuntu. There is no spillage or any accident on the laptop.

I think the issue might be that I did something, maybe deleted/cleaned something I wasn't supposed to. I think this because the problems only started a few days ago when I typed these in the Terminal:

$ du -sh ~/.cache/thumbnails

$ sudo du -sh /var/cache/apt

$ sudo apt-get clean

But please do correct me if I'm wrong. I'm new to Linux.

Please [edit] and post detailed hardware specification and while at that clean up your post by removing unnecessary comments, tangents and distractions.

Looks to me like you have conclusively demonstrated a hardware fault: If the problem had been your installed Ubuntu, then the USB installer would have worked properly. Contact your hardware vendor for warranty service.

Why are you logging in as root. By default the root user is not even fully configured in Ubuntu and is not intended for everyday use. What version of Ubuntu are you using?

Sorry my terminology of Linux is non existant. I don't know if it's logging in as root or not. I just heard the word once and remembered what it looked like. It's a complete black screen and a small blue line asking for password - I don't know if this is just normal loggin or root login. I don't know how to turn this off. I know nothing about Linux and only installed this a week or more ago. I am a complete newbie.

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.
