I just bought a MacBook Pro in Oct 2021 and just yesterday I got a sudden green line that's going right down near the middle of my screen. I've tried restarting my computer to see if that would help, but it's still there. It's not a big deal to me right now, but I know this will start to be irritating to work with.
MacBook Pro 13″, macOS 10.15
Most likely a vertical line indicates a hardware issue with the LCD Panel. Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate. As long as there are no signs of accidental damage, the repair should be covered under warranty. You definitely want to have this checked out as soon as possible in case it is covered by the warranty since you never know what may happen later that may appear to be accidental damage.

As of Monday, it is now not displaying anything and the line looks a little like orange now... ugh I have never had this issue with my previous MBPro. Finally being able to take it tomorrow, so we'll see what they tell me.
I just got the exact same problem today, with mbpro that I bought in October 2021. as well.
same as you, green line, related to display.
