High cpu usage from system-udev on charging laptop and heating to 60C

The laptop generally felt very hot while charging and I chose to ignore it, but I was checking something else and found systemd-udev using significant cpu. So I tried running udevadm monitor and I had a lot of events (3-4) per second being printed and non when not charged

The following is its output:

Edit: This is a hp Victus 15-fb0xxx

Edit 2:

❯ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
