what are those squares? but it looks like its exist in filesystem issue…
do you have manjaro live usb? it would be better to repair it from there
I don’t know, but I can do it.
if anything, I have os esch encryption
live usb yes
boot into manjaro live usb, make sure you are connected to internet, open terminal and post output from:
lsblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME
you dont need to post pictures, you can just copy the output here, it would be better…
so chroot:
sudo cryptsetup -v luksOpen /dev/nvme0n1p1 cryptDrive
sudo mount /dev/mapper/cryptDrive /mnt
sudo manjaro-chroot /mnt
if there were errors, post them here, if not, post output from:
pacman -Qm
pacman -Qs nvidia
EDIT:
also post output from:
ldconfig
if its too long, dont post it…

and use formatting for the outputs, click this icon in editor </> and copy the output there;
or use:
```
your output here

remove these:
pacman -R linux518-headers linux519-headers manjaro-documentation-en manjaro-firmware linux515-nvidia nvidia-utils
and then post output from:
ldconfig
if its too long, dont post it…
shows nothing on output ldconfig
so now install video drivers:
mhwd -i pci video-nvidia
if there are errors, post them here
sh-5.1# mhwd -i pci video-nvidia

Error: pacman failed!

so use overwrite:
pacman -S lib32-nvidia-utils libxnvctrl linux515-nvidia nvidia-settings nvidia-utils --overwrite '*'
if no errors, post again output from:
mhwd-kernel -li

Error connecting: Could not connect: No such file or directory
error: command failed to execute correctly
It was successful but there were such lines)
sh-5.1# mhwd-kernel -li
Currently running: 6.1.19-1-MANJARO (linux61)
The following kernels are installed in your system:
* linux515
* linux62-rt
ok so it didnt install drivers for the linux62-rt, have no idea why… so just remove it, otherwise you end up again with a black screen:
pacman -R linux62-rt
and just to be sure reinstall the 5.15:
pacman -S linux515
if no errors, exit chroot:
exit
reboot and test … if everyhting works, you can install the latest stable kernel 6.1:
sudo mhwd-kernel -i linux61
i installed linux 515 rebooted the problem with booting the system did not go away then i installed mhwd -i pci video-nvidia successfully but the problem remained with booting the system
Welcome to the forum! 
Please edit your topic title and use words, not invented, meaningless abbrevieations. No one knows what oc means. Please see How to Post.
First uninstall the NVIDIA driver you installed from their website, then install it in the way you’ve been instructed.
There’s a reason why that should normally never be used.
can you tell me how to remove it?
If you figured out how to install it, you can figure out how to uninstall it the same way. 
did you actually installed the nvidia from their website? if yes, there should be instructions on how to remove it…
before my system broke down, I installed the driver for a long time according to this instruction https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-manjaro-linux maybe it still costs, but there is no information on how to remove it .
there are several methods on how to install it, one is using mhwd tool, and the other is from the nvidia site, so which method did you use?
