I was running Ubuntu 20.04.1 and suddenly my laptop would freeze and lock up completely. It is not responsive to mouse and keyboard. I tried Alt+F2 to restart GNOME Shell.
The background video playing on the browser (YouTube) also stops, so I pressed Ctrl+Alt+Del. My SSH connection was also not working at that time.
I tried changing my GRUB to intel_idle.max_cstate=1. I deleted the additional NVIDIA drivers and just worked with my Intel graphics card, but it also didn't work. I tried searching for logs at the time when it froze, but I found nothing.
I dual boot windows and I have 8 GB of RAM and 2GB swap space. The freeze happens at random times. It sometimes freezes when I just login where there are no programs running. I even changed my kernel version. I am sure that it is not problem with my hardware. Windows works fine. I have tried almost everything I found on internet but nothing worked. Can anyone help me Please?
My laptop's specs are:
Device name: Inspiron 7591
Memory=7.6 Gib
Processor=Intel Core [email protected] x 12
Graphics Intel UHD Graphics 630
//Other Graphics : Nvidia 1650 GTX (I am not using this one)
Gnome 3.28.2
OS type 64 bit
Disk 105.2 GB
Since nothing worked for me I switched to 18.04.01, but the same problem arised.

And similar. I am not sure what this crash is.
Today, 2021 Jun 11 6:57, my laptop froze again and I got the logs form journalctl just few seconds before. This is very long so I uploaded it in a pastebin.
Hope someone will find the problem. I couldn't understand it.
