Hi ,
did you try to install it over pacseek. If you dont have pacseek you can install it in the terminal sudo pacman -S pacseek . (linux firmware is preinstalled) this or below rtl8761 usb-dkms i would try if i had the chip.
For this issue Garuda use Dracut for update or rebuild initramfs.
Updated initramfs sudo update-initramfs -u → Still fails
sudo dracut-rebuild
P.S you should update your bios also for security patches
