I'm using cachyOS, which is based on Arch Linux, and I'm trying to shrink my main hard drive, which currently has about 180 GB of space—three times more than what I'm actually using. However, when I attempted to use KDE Partition Manager to do this, it didn't work after waiting for 30 minutes and just caused my laptop to lag. After a restart, the hard drive space was unchanged. I'm really new to Linux, so I want to ensure I do this correctly and safely, without messing anything up. Any advice on the right tools or methods to use?

Great tip about GParted Live! Just to clarify, you'll indeed need a bootable live environment since the system can't resize partitions that are currently in use. After you boot into GParted Live, you should be able to see your partitions clearly and adjust them safely.
To shrink your main drive, you definitely need to unmount it first. Additionally, make sure to back up all your important data to external storage before trying anything. I recommend using GParted Live; it’s a reliable tool for partition management and allows you to do this without the OS being active.
