[Solved] System hangs on shutdown

Hello!

When I shutdown or reboot, this shows up on my screen:

[  OK  ] Stopped Authorization Manager.
[  OK  ] Stopped Daemon for power management.
[  OK  ] Reached target Final Step.
Starting Power-Off...
[$TIME] INFO: task Xorg:584 blocked for more than 120 seconds.

$TIME is just the time the message is printed at (for example: "12287.625370")
The time difference between the first info message and the last is about 8 minutes, and it doesn't seem to be printing more after that, but the system continues to hang.

This sounds like it could be related to Xorg, so here's some info:
DM: LightDM (greeter: GTK)
WM: i3

Edit 2020-04-24:
I forgot to update this, but I kept getting this issue and I eventually figured out that it's caused by the NVIDIA proprietary driver.
