We have the same crash that spikes sometimes to thousands of crashes and than disappears magically! We do use a webview inside a swiftUI where we load some HTML with Javascript. The size of that is determined by the moder KVO way:
webView.scrollView.publisher(for: \.contentSize)
.removeDuplicates()
.sink { [weak self] contentSize in self?.contentSize = contentSize }
.store(in: &cancellable)
I'm not sure if this causes the problem with a specific HTML payload!
@ivavilov are you using similar code?
