100% CPU usage after updating my laptop which causes my laptop to freeze

95. Swap:

96. Alert: No swap data was found.

You will also experience lockups/crashes when you hit that 11.5 GB of memory limit, because you have no swap.

My suggestion these days is usually zram. Heres another post where that is outlined;

Continuing the discussion from Awful performance since install:

@cscs

sudo pacman -Syu zram-generator

Then edit the configuration file. (use your preferred editor)

sudo micro /etc/systemd/zram-generator.conf

You want it to look like:

[zram0]
zram-size = ram / 1
compression-algorithm = zstd
swap-priority = 100
fs-type = swap

You may want to ensure zswap is disabled as well. One way is to add to the boot options, at /etc/default/grub the option zswap.enabled=0.
That is to add it to one of the CMD lines so that (Assuming no other options) it would look like:

GRUB_CMDLINE_LINUX="zswap.enabled=0"

Then run

sudo update-grub

And reboot.
You can check the configured swap/zram using

swapon

zramctl
