If you have recently installed linux and you are facing any freezing problem when connected to the WIFI, chill up buddy. I am here for you.

Do not panic. There is nothing wrong with the distro nor your device. Just the kernel using the default wifi driver it came with.

I would recommend you run a system update first.

sudo pacman -Syyu

If problem still persists, then follow the next instructions.

How I Solved Mine.

• I tried installing the drivers manually. https://tutorialforlinux.com/2020/01/12/step-by-step-arch-linux-realtek-rtl8821ce-driver-installation-guide/

The link above should help.
For garuda linux users, you can visit the add/Remove Software to download the drivers.

• I went into the /etc/modprobe.d/ folder and created a file blacklist.conf. You might have to root the folder before you can create the file.

• Inside the file I only wrote:
  

• I then went to /etc/default/grub and added pci=noaer to the kernel parameters.
  

• Open terminal and run
  

sudo update-grub

then

sudo reboot

Problem solved!!! Screen freezes no more.
I hope it solves yours.
