When used inside a TabView, any loading of a WebImage will immediately cause a crash. Here is the code that causes the crash:

TabView { Text("testing") .tabItem { Text("test") } WebImage(url: URL(string: "https://raw.githubusercontent.com/SDWebImage/SDWebImage/master/SDWebImage_logo.png")) .tabItem { Text("test2") } } 

I am using Xcode 12.0 with iOS 14.0, with SDWebImage 5.9.0 and SDWebImageSwiftUI 1.5.0.

Below is the stack trace:
