Why would changing hostname trash icon theme?

OS: Vanilla Arch
Kernel: 6.8.6-arch1-1
WM: awesomewm (X11)

On a machine at work that was just standing there powered off for years I decided to install arch so it would be useful.
After everything was done I also install candy-icons in '/.local/share/icons/' and ran a 'gtk-update-icon-cache -f -t' to for the cache.

All was OK until I saw that the hostname was wrong so I changed it, not by using hostnamectl tho but manually changing the hostname file.
When I restarted pcmanfm did don't use cancle-icons so I did the cache thing again, still nothing.
Fiddled with this for hours but it just won't work.
Using 'lxappearance' will not use the thing I set, like Arc-Dark when restarted and the gtk-3.0/settings keep getting wrong icon theme.

wtf is this?
Why would a hostname change F' this up so bad I can't use it anymore not setting it with lxappearnce or by manually change it in gtk2.0, gtk-3.0 and gtk-4.0

Update: Remembered that before rebooting I had chromium running and running that after reboot it told me that it couldn't start as it was running on an other profile but the profile is the user, right?
Could it be something like this?
