because all the processes run on the main thread

Not actually. Only the render part and query cache happended on main queue, it's by design

My SwiftUI app hangs after adding WebImage to the screen. I have displayed a list of WebImages in a ScrollView and LazyHStack. I checked the Instrument tool, it displayed app processes on the main thread. After making the load() and cancel() methods asynchronous, my app works smoothly.

Can you provide your xctrace result ? With your App.dSYM and SDWebImageSwiftUI.dSYM is better (to symbolicate the symbols)
