Yesteday I updated my Manjaro linux install, after that I went to sleep. I was going to boot back into Linux to use on school work and see the corrupted FS error, I looked up some guides and noticed pretty much all of them use FSCK but when I try to use that it says unknown error. I don't have Time Shift setup.

Edit 1: I just made a Live USB on Windows and fixed it with fsck

Boot from live media and see if you can repair it.
Make sure that you run fsck on the correct partition, not the swap or UEFI.

You left a lot out. Are you booting from a majaro install and not a USB/Optical disk?
How did you update manjaro? With pacman? What is in pacman's log?

Are you partially updated? How long since you updated? Did you have /boot mounted when you updated? Another words is /boot on a separate partition?

Is this a filesystem error and not a grub error? Grub can be fixed.

When you boot from a live install media, look at:
fdisk -l
fsck

Could also be a hard disk dying. I would boot from live media and check it, if the filesystem is damaged.

I already had Manjaro installed on a NVME drive. I updated from Add or Remove Software, I highly doubt my SSD is dying cause I I got it replaced with my laptop. Im gonna go find a usb and flash Manjaro to.
