Hello,
I was facing the same problem on an other distro wich using chaotic-aur repository. This repository had been maintained by Garuda team at the time but now, this distro is dead and no longer maintained.
The solution i found is to comment or delete the chaotic.aur lines in the pacman confi file, like this 🇦
1) #sudo nano /etc/pacman.conf
2) Comment the repos 🇦
#[chaotic-aur]
#Include = /etc/pacman.d/chaotic-mirrorlist
3)# Now, write the changes to pacman and sart updating 🇦
#sudo pacman -Syu
And everything should work flawlessly again.
Hope this helps. Let me know if the problem is still.
