is linux-firmware installed? If you're dual booting, make sure fast boot in Windows is disabled.

Test the LTS kernel, and maybe post a full log:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

This time, I formatted my laptop's hard disk to remove both Windows 10 and Arch Linux. Then, I reinstalled Arch Linux in EFI mode with the Linux-zen kernel, Linux-firmware, and NetworkManager. I did not reinstall Windows 10; I only installed Arch Linux. It will show same issue... No change ?

Yes, there's no reason that would help if fast boot is confirmed to be disabled. It's very possible to be a kernel bug, test the LTS kernel and post the output I asked for, if you don't have an internet connection do

sudo journalctl -b > /tmp/journal.txt

and usb walk that file to some system that allows you to post the contents.
