Tanks to the people who mentioned Sherlock. After quitting the Sherlock app it started working properly again! I think the issue comes from the fact I was using a deprecated version.

Hey, It goes away, but I cannot do async work when tapping the button. (The real-world application is to call an async func at this point) Does that mean it is impossible to use async functions pre-iOS 15 in swiftUI ?

Great news, It looks like issue is fixed on XCode 14.3 ! :D
