Can't turn on Mint: tty1 login: Could not find valid key in the user session keyring

Hello, I can not get in to my Linux Mint system. It requires a tty1 login whenever I turn on my laptop and then says it "Could not find valid key in the user session keyring..". I have attached an image of the commands and rewritten them below.

I am a dual boot user with Windows 10 and Linux Mint 19 Tara 64bit for over a year. My laptop's model is Asus TP309NAH. I have the minimum experience of working with both of them. I was having several problems with Linux Mint. I'm going to state a detailed history of the last few things I did guessing they might help finding out what went wrong.

I had a long list of available updates on the Update Manager of Mint. I couldn’t update them due to a "Repository does not have a release file" error.

I was also getting the "low space on 'filesystem boot'" warning. So I applied 1,2,3,5,8,9 points from (https://easylinuxtipsproject.blogspot.c ... t.html?m=1) article to clean up some space. I also uninstalled some softwares I do not use anymore. I restarted my laptop several times during this session. It was working alright.

Then I realised my Libra Office was failing to save any odt file. It was showing a "general input/output error" whenever I tried to save them. It also failed to open any previously saved odt file saying they were corrupted.

I didn’t do anything after that and shut down my computer. And failed to turn it on the next morning. It does let me select Linux Mint system, then the mint-logo shows up. After that, it asks for some kind of tty1 login. I enter my password but it shows the following commands:

Linux Mint 19 Tara athoi–TP203NAH tty1

athoi–TP203NAH login: athoi

What should I do now to turn mint on?

PS. Windows 10 is working alright.
