Maybe, you can update your linux kernel.
I update my kernel use commands below.

sudo apt update
sudo apt-get install linux-image-5.15.0-41-generic
sudo apt-get install linux-headers-5.15.0-41-generic
sudo apt-get install linux-modules-5.15.0-41-generic
sudo apt-get install linux-modules-extra-5.15.0-41-generic
sudo update-initramfs -u -k all
sudo update-grub

Your kernel version is too old.
Please run upgrade your kernel version 5.0.0-23-generic, 5.4.x or 5.8.x.
