Hi Bodhi_2021,

Thank you for using the Apple Support Communities. It looks like your MacBook Air has a vertical line in your Dock and we would like to help!

We'd like for you to try the following steps and check to see if the line is still there after each one:

Close out of all open apps: Quit apps on Mac
Restart your Mac: How to turn your Mac on or off
Update to the latest version of macOS Big Sur (11.3.1): How to update the software on your Mac

We hope this helps!

Take care.
