I've just set my PC moniter as primary screen when I plug in my MacBook (Air 2020) but it keeps rearranging my Homescreen.
When I rearrange it so it fits my external display and unplug my laptop it will place the apps on top of each other so I that doesn't work.
Can I prevent this from happening?

Because it's a laptop with its own screen, as soon as you unplug your Primary screen, the internal once again becomes Primary & all windows will migrate to it.
Re-connecting the other display it will then once again reassign it as Primary - but the 'damage' has already been done & it will not be able to correctly place the windows back where they were.
You may benefit from using a third party window manager. There are a few listed in the answers to this question - Do any window managers allow me to snap windows to the sides of the display?
