Also just as a hint, you don’t need yay -Syyu. Just use yay without any arguments for updates. As a default yay hands down -Syu to pacman.
The double yy in -Syyu also is not needed. Those flags are handed down to pacman by yay. It forces a refresh of the pacman database, even if nothing has changed. That is usually not necessary and puts more stress on a repo than it needs to.
