linux RAID 10 Array not mounting / working (Linux)

[Gray The Alien]

Hi. After a restart yesterday my system would not boot and went into Emergency Mode, so I had to clear my /etc/fstab to be able to boot again as there was a problem with the mounting of the RAID-10 disk.
After that I checked the Disks application and could not even manually mount the disk. I have tried to fix this issue for a good while now but I'm not tech-savvy enough to find the solution since I'm a Linux n00b.
Any help is very much appreciated.

I'm adding a screenshot from the Disks application in Pop!_OS and from the terminal where I checked the disk with mdadm.

The state looks funky here:

Just posting this here if anyone (myself included) in the future has this problem. I ran this command:

mdadm --assemble --verbose /dev/md0 /dev/sda /dev/sdb /dev/sdc /dev/sdd --update=devicesize

And I almost fell out of my chair as the array became alive again. It would not mount properly tho because it said it needed to be cleaned, so I ran this command:

sudo e2fsck /dev/md0 -y

And it's now okay again.
