FnLock key not working on Lenovo Yoga 9 14ITL5

Whenever I incur the FnLock hotkey by pressing Fn+Esc, the process kworker/0:1+kacpi_notify will appear and start to consume a significant amount of CPU resources, not stopping until I fully reboot my system. Through further investigation, I checked the logs of the acpid daemon on my system with 'journalctl -fu acpid' and noticed this message being spammed multiple times per second

Jan 31 22:02:20 arch root[46810]: ACPI group/action undefined: 8FC0DE0C-B4E4- / 000000d0

I still have no idea what's behind this.

Kernel: 5.16.4-arch1-1
DE: Plasma 5.23.5
CPU: Intel i7-1185G7

I've noticed that while this issue is present on the 5.16 linux kernel and the 5.15 linux-lts kernel, it isn't present on the linux 5.14 kernel leading me to believe that this is an issue only present on linux kernels newer than 5.15.
