Lots of functions stopped working after running Sudo Pacman -Syu and r

Functions like internet or audio output/input simply stopped working after I ran sudo pacman -Syu and rebooted

When I dmesg, some are normal but a significant part of it outputs the same thing:

 version magic '6.9.10-arch1-1 SMP preempt mod_unload ' should be '6.9.8-arch1-1 SMP preempt mod_unload ' 

How can I solve this? I cannot connect to the internet, and I use an ethernet cable

Thanks in advance

looks like you boot the wrong kernel - which often happens when /boot is not mounted during a kernel update
I would boot archiso - mount the system - arch-chroot - reinstall kernel - check bootloader config - reboot

You can verify the condition cryptearth described by comparing the version numbers reported by uname -a and by pacman -Q linux  (assuming you are running the stock kernel.  If not, change that command as appropriate).  I bet they are different -- that is your problem

If they are different, you can fix it by ensuring your boot partition is mounted on /boot (it won't be, be check it with mount | grep boot.  That command probably will report nothing.  Mount it and check again.

Then, just run pacman -S linux to reinstall the kernel from your cache.

Then, fix your /etc/fstab to mount the boot partition so this never happens again.

Edit:  Oh, Welcome to the Forims.

You still will want to fix your /etc/fstab file to mount your boot partition on /boot or this will happen again with the next kernel update.
