I have set up 3 displays on my Mac Studio 2022 M1.
Whenever I restart the machine or wake it from Sleep, the displays rearrange themselves and reset to the wrong resolution.
How do I get my Mac to remember the display settings?

To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, System Settings if Ventura, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
This problem is not limited to your Mac Studio. macOS has had this problem with multiple displays as far back as 10.14 Mojave and it has never been resolved.
It might help to send Feedback, but don't hold your breath.
I have used multiple displays for years and use a few work-arounds to limit the need to rearrange my work space.
1) Only Restart when required for macOS updates.
2) Disable Mission Control Spaces, ScreenSaver and Lock-Screen.
3) Disable Automatic Computer Sleep and only allow the displays to (sleep) turn off.
