Manjaro does not boot after installing a new Kernel-dropped Into emergency shell, for people who think they have a big problem but are actually just noobs

Hello,

I have Manjaro KDE Plasma on my Dell XPS. Its 2 days since it happened, i did the new updates like usual and my Laptop then asked me to install a new Kernel, because something doesnt work with an update. I opened the Manjaro Settings and tried to install a newer Kernel, after it completed, I was told to reboot to finish the update. I did that, and received a terminal screen with this message:

I searched for a bit online, and in all related threads people seem to be able to run commands. I failed, its not working at all, i really dont understand the problem. I mounted my partitions from a live OS but it did nothing. The commands didnā€™t work. Iā€™m sorry Iā€™m very desperate, also because I normally am probably lucky and although i have no idea, I get things working somehow. I would really appreciate any help.

So, my questions are these:

What is the problem, and how can I avoid this in future?
How can I fix this issue for now? (I really donā€™t want to format and reinstall)

Is all my data gone? If not, how can I recover those?

Iā€™m pretty new to Linux, so Iā€™ll much appreciate if you answer in a easy to understand way.

Thank you!

this is the issue:
ERROR: device UUID-4b2b26ab-f541-466e-a7f6-fe7c5b45957
it cant find one of your partitionsā€¦
do you have a manjaro usb? if so boot into, chroot:
sudo manjaro-chroot -a
then post formatted output from these commands:
cat /etc/fstab
blkid

And please use preformatted text, my eyes hurt. (isnā€™t there some guide to read or something when you register on the forum?)

You should be able to.

it looks good ā€¦ can you access your manjaro partition?

What do you mean by ā€œaccessā€

from live usb use dolphin or whatever file manager and open for example your home folder where you have your filesā€¦

no i cant do that

is there some error/warning? is it even detected?

When i open dolphin or my folders from live usb?
Itā€™s just empty

i mean on the left side in dolphin under devices, if you click on your manjaro installation, can you access that, not live usbs foldersā€¦

im rly sry for giving you a hard time
An error occurred while accessing ā€˜Homeā€™, the system responded: The requested operation has failed: Error mounting /dev/sda1 at /run/media/manjaro/MANJARO_KDE_2115: /dev/sda1 already mounted or mount point busy
thats what i get

its okā€¦ but i dont know whats with itā€¦ post output from:
