System freezes on boot and Plasma freezes the window manager occasionally

theres no reason to save the logs, just run the command when in chroot, and copy the output here

Hi, still havenā€™t done this so far. I will do soon.
But during an update over terminal I have received this info:

Adding boot menu entry for UEFI firmware settings...
Root filesystem isn't btrfs

It was translated by me with translate cause these messages appear in german sometimes.
Can you check? It should support your idea, right?

it looks okā€¦ so did the reinstall of grub helped?

Hi, I had many other challenges, had to relocate and all.

Till today I havenā€™t tried the steps of your solution.
Am still using the boot stick to get into a running system.

So, to go on with trying to fix this, I need to do this from your post, right?

Could you also take a look at the grub conf?
I made a bigger upgrade after a longer time waiting to do it. And it seems grub is installed now.
But why is it set to saved when the corresponding line is not commented out?

cat /etc/default/grub

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR="Manjaro"
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=55fbbe79-fe73-437c-8888-f1eafbd43f72 udev.log_priority=3"

yes do that:

and the grub output looks okā€¦
