The source for that terminal command suggest you disconnect your external display, so that you can type of the built-in display. Then you have 20 seconds lead-time to re-connect your display, while killing WindowServer logs you out.
This blog (by a self-proclaimed Android and Windows specialist) appears to be an early source for the kill WindowServer work-around:

.
using the command
sudo sleep 20 ; sudo kill -9 $(pgrep WindowServer)
was the best workaround I have found so far.
Some people say that 13.0.1 fixed it, but it didn't for me.
But this is a temporary workaround.
Ventura - External Displays not working - Apple Community
Ventura 13.0.1 was issued Wednesday, 9 Nov 2022,
Any changes?
nope, unfortunately not.
Updating to 13.0.1 didn't help for me.
Some users are reporting temporary relief by force-quitting the WindowServer process.
This will log you out, but on logging back in, often the screen is not scrambled.
Only work with usb-c to HDMI port but the resolution is lower than previous (5120 x 1440 with usb-c to Display port) under both of 13.0 and 13.0.1.
